The Italian network "IMA_CAN1" has been added to the ISMN.

IMA_CAN1 is a soil moisture network located in the Piedmont region, in the north-west of Italy, and hosted by the Institute for Agricultural and Earthmoving Machines (IMAMOTER) of the Italian National Research Council (CNR). It is installed in three vineyard plots, with different inter-rows soil management. The plots are also monitored for runoff and soil erosion.

The network consists of 12 stations measuring soil moisture and soil temperature. Observations are available from August 2011 until December 2015.

We would like to thank Marcella Biddoccu and Giorgio Capello for providing the datasets and for their support during the implementation process.

We are very happy to announce that funding for the next 14 months was granted by ESA! 

The ISMN has been kindly supported for many years by different ESA programms (SMOS Earth Observation Program and lastly IDEAS+). ESA has kindly included us in the new Quality Assurance for Earth Observation (QA4EO) programm starting this November 2019 until end of December 2020. This will give us the means to add new networks and datasets, and maintain the functionality of the ISMN. Currently, we are exploring alternative long term funding possibilities to continue the operation of the ISMN after this date, but we have no commitment so far. We are still confident that we'll find an appropriate solution on time but if worst comes to worst we may have to reduce the services provided by the ISMN (e.g. the implementation of new networks and network updates) until further financing is ensured. Any suggestions from your side would be highly appreciated!

We greatly thank ESA, our data providers and of course our users for their support and interest.

Any suggestions or ideas from your side on how to keep the ISMN running after 2020 are always welcome and can be posted with a new entry in our Forum

The data of the Romanian network RSMN has been updated until 15.10.2019. Please note that at the stations Oradea (15080), Satu Mare (15010), Slatina (15434), Rosiorii de Vede (15470), Alexandria (15489), Iasi (15090) and Calarasi (15460) the soil moisture and soil temperature sensors have reached the end of their battery life. The responsible personnel has already been notified by Eduard Luca and hopefully the issue will be resolved shortly.

We kindly thank Eduard Luca and Andrei Diamandi for providing us the data.

Reoccurring setting changes for 44 stations of the US near -real time network "SNOTEL" starting already last year (2018). These stations are now integrated in the near real time update again since the setting changes seem to be stable.

Unfortunately, five of these stations are not providing soil moisture and soil temperature values anymore. For further information please have a look here: Forum SNOTEL .

The data of the Romanian network RSMN has been updated until the 15th of July 2019. Please consider that there is no data provided for July 12 likely as a result of a connection error to the insitu stations. Soil moisture and soil temperature data are available again from June 4 onwards for the station Slatina!  

A big thank you to Eduard Luca and Andrei Diamandi of RSMN for providing us with their data!

The data of the Danish network "HOBE" have been updated and are now available until 13th March 2019. Please note that not all the stations are updated to this date. Furthermore, there are some data gaps (see forum).

We kindly thank Frederik Uldall and Karsten Høgh Jensen for providing the new data!

The datasets of the German network "TERENO" have been updated.

For the stations Wildenrath, Gevenich, and Merzenhausen data is now available until 02-Apr-2019. Soil moisture and soil temperature data collected at Wildenrath station are partially odd and show gaps (see forum). Nearly the same partly applies to Merzenhausen (see here). Schoeneseiffen data is now available until 25-Apr-2019 data gaps for soil temperature (see forum).

We would like to thank Jürgen Sorg for providing the updated datasets!

There are now 7 additional stations available for the network SCAN. Two new stations are located in Alaska and five are located in Missouri. The measurements of these stations start in 2018 and will be updated in near real time. In total the network contains 239 stations.

The data of the Romanian network RSMN has been updated until the 15th of April 2019. For the station "Oradea" soil moisture suspiciously drops and shows characteristics of a "low plateau" (see forum). Moreover, please consider that another 24 hour data-gap in the entire network has occurred on the 11th of April 2019, likely caused by connection errors to the in-situ stations.

We would like to thank Eduard Luca and Andrei Diamandi for providing us the data!

This python package reads data from the ISMN data format. It is now at version 0.3 and can be installed via pip.

The new version of the package incorporates the following developments:

·         The user can fully exploit the ancillary layers of the ISMN data by accessing the land cover and climate class information stored in the metadata. These fields are returned in the metadata of each station and can also be used to filter the stations chosen for analysis.

·         The package now uses cartopy instead of basemap for plotting routines. This is due to basemap no longer being supported past 2020.

·         Please be aware that only ISMN data in CEOP  format is supported not in the header+values format which also can be choosen for the ISMN data download. For more information on ISMN download formats please have a look here: https://ismn.geo.tuwien.ac.at/en/data-access/.

The package is distributed via PyPI: https://pypi.org/project/ismn and the source code is available on github: https://github.com/TUW-GEO/ismn.

We are pleased to invite you to participate in the ESA CCI Soil Moisture user workshop, which will be held on 15 November 2018 at the Technische Universität Wien, Vienna.

Since 2012, TU Wien, EODC, VanderSat and their partners have successfully implemented ESA’s Climate Change Initiative for Soil Moisture. ESA CCI Soil Moisture produces the most consistent long-term global soil moisture data record based on active and passive microwave sensors and currently provides a set of products from 1978 to the end of 2017. ESA CCI Soil Moisture has received over 6000 registrations for download, has directly supported the publication of over 200 peer reviewed papers, and feeds into several operational services.

The objective of this workshop is to:

  1. give an overview of ESA CCI Soil Moisture and its support to ESA’s primary CCI programme goals; 
  2. demonstrate how ESA CCI Soil Moisture has supported international climate observing activities (e.g. IPCC, Global Climate Observing System);
  3. demonstrate how ESA CCI Soil Moisture has advanced science in climate research and other domains;
  4. show how ESA CCI Soil Moisture supports the operational services provided by C3S and others;
  5. identify new applications based on operational long-term soil moisture products,
  6. show how ESA CCI Soil Moisture has led to Austria taking a key role in the scientific development of Essential Climate Variable products from Earth observation.

The workshop is open both to presenters and non presenters. The workshop is free of cost and includes lunch at the location.

Abstracts can be submitted online until 4 October 2019. Submission details can be found at http://cci2018.geo.tuwien.ac.at/call-for-abstracts/

Science lead CCI Soil Moisture

Soil temperature and precipitation data from GLDAS Noah is used within the ISMN quality control procedures to evaluate the plausibility of in-situ soil moisture readings (flags D03 and D05).

GLDAS version 1.0 (dataset from 2000 onwards) discontinued by end of 2016 but a new version 2.1 (dataset from 2000 until near real time) has been released. Thus, the integraion of the new GLDAS version 2.1 became necessary.

This change brought us the opportunity to integrate also soil temperature datasets in deeper layers (up to depth of two meters) for version 2.0 (datast from 1948 to 2010) and 2.1 . Within the upcoming months it is planned to reprocess the entire ISMN database due to the this development.

The datasets of the American network "iRON" have been updated, and are now available until mid May 2018.


Besides, a new station was added to the network, namely "Glassier Ranch". This station is located at an altitude of 1970 m, and is surrounded by tall grass. Soil moisture readings might be impacted by nearby irrigation. Data for the "Glassier Ranch" station are available since the end of July 2014.

We want to thank Elise Osenga for providing the updated data and her support during the implementation process.

The datasets of the German network "TERENO" have been updated.

Data for the stations Wildenrath and Gevenich is available until 17-Jul-2018. There is a data gap for the station Wildenrath from 9-Mar-2018 to 10-Apr-2018 and some of the sensors show an unrealistic behaviour.

For the station Merzenhausen data is available until the end of May 2018. From January 19th 2018 only two of the four precipitation sensors and one of three coupled soil moisture and soil temperature  sensors, present at every depth (5, 20 and 50 cm), provide observations.

We would like to thank Jürgen Sorg for granting access to the updated datasets.

The datasets of the US network "PBO_H2O" have been updated until 2017-12-16 and has been set inactive as of this date.

Data for this network was expanded from 2011 < near real time to 2006 < near real time. This network is based on in situ retrivals on the average of multiple GPS statellite tracks. New quality control methods on their raw data were applied: 

- negative VWC (volumetric water content) is not allowed

- VWC < 0.55 will not be allowed

- Only in situ data is stored when more than 5 satellites are present

- soil moisture data is removed when the vegetation water content < 2 kg/m/m

Stations okl1(data until 2016-05-02), p130 (data until 2016-06-11) and p775 (data until 2017-05-27) have been removed due to their unreliability.

Thank you so much Kristine Larson for sending us the data and explaining your quality control methods and for always replying so promptly to our questions.

The French network "FR_Aqui" has been added to the ISMN.

FR_Aqui is located in the Aquitaine region, in the south-west of France, and hosted by the National Institute for Agricultural Research (INRA). The network consists of 5 stations measuring soil moisture and soil temperature in 6 different depths. Observations are available from January 2012 until January 2018.


We would like to thank Christelle Aluome and Jean-Pierre Wigneron for providing the datasets and for their support during the implementation process.

As the COSMOS data server is up and running again  the ISMN is providing the COSMOS data again in near-real time.

We kindly thank Eduard Luca and Andrei Diamandi for providing us the data.

22-25 October 2018, George Masion University, Fairfax Campus (Washingtion DC area), USA

The purpose of the 5th Satellite Soil Moisture Validation and Application Workshop (October 24-25 2018) is to discuss and reconcile recent advances in the development, validation and application of global integrated soil moisture products that utilizes satellite observations. The workshop series is unique by bringing together satellite soil moisture users and developers to focus on derivation, validation and exploitation of soil moisture data from both passive and active microwave satellite missions (SMAP, SMOS, ASCAT, AMRS-2, Sentinel-1, and other legacy missions) and electro-optical instruments (MODIS, VIIRS, Landsat et al.).

The workshop will be held in conjunction with the SMAP Cal/Val workshop (October 22-23 2018).

More information can be found on http://genri.gmu.edu/smw2018/

The Chinese network "CTP_SMTMN" has been updated until 19th September 2016.

We would like to thank Dr. Zhao Long and Prof. Kun Yang for providing the new data.

Due to the replacement of soil moisture and soil temperature sensors at the French network "SMOSMANIA" the data was reprocessed for 2016 at stations Urgons, Creon dArmagnac, La Grand Combe and Barnas. Station Pezenas has been moved 200m from its former position. Considering this change we have now a station called Pezenas_old at the old position (with data from 2008-11-22 until 2016-04-18) and a new station called Pezenas at the new position (with data starting from 2016-04-19 until end of 2016) implemented in the ISMN. 

We kindly thank Jean-Christophe Calvet for informing us about the changes.

All datasets of the network "SOILSCAPE", except from stations node8xx, were reprocessed due to recalibration by the data provider. Additionally, the datasets have been updated until October 2016.

Furthermore, 35 new stations were added to the database. They are arranged in clusters and are located in California and Arizona.

The datasets of all stations of the German network "TERENO" were reprocessed and updated until end of September 2016. In addition, some new soil moisture and precipitation sensors were added. And, the naming of the provider quality flags changed.

From March, 10 2015 to April, 14 2015 the soil moisture and soil temperature data of the station 'Wildenrath' show odd values. For more information please have a look at the forum.

We received datasets from a project conducted in Uzbekistan during 2011, operated by Uni Würzburg. All seven stations provide soil moisture measurements, for one station also meteorological observations are available during 2010 and 2011. Although soil moisture was not observed continuously, the measurements are still a valuable contribution since no other recent observations are available in this region.

We want to thank Patrick Knöfel for providing the datasets.

The new network "BIEBRZA_S-1" operated by the Instytut Geodezji i Kartografii is located in the northeast of Poland and consists of 30 station. They are organised in three clusters of nine stations with soil moisture measurements and one weather station each. The stations are placed in a marshy surrounding. Therefore the soil moisture values are unusually high. 

We want to thank Jan Musial  for providing the data and his support during the implementation.

The precipitation data of the network DAHRA were reprocessed due to erroneous shift in the data sets in the years from 2013 to 2015. We want to thank Torbern Tagesson for recalculating and providing the updated data.

The station 'Prades-le-Lez' was updated until end of 2015.

During the year 2015 the soil moisture sensors of the stations 'Barnas', 'Berzeme', 'Prades-le-Lez' and 'Villevieille' were replaced by new sensors. This changes can  now be found in the ISMN. Additional,we were informed that the soil temperature at all stations is getting measured with the sensor PT100 from Pentronic. Therefore, the soil temperature sensor name of all stations was corrected to the right sensor.

We would like to thank Jean-Christophe Calvet for providing the updated datasets and the information about the changed sensors and sensor names.

The datasets of six stations ("WSMN-1" to "WSMN-6") of the network "WSMN" are updated until end of February 2016. Furthermore, a new station "WSMN-8" was added. It provides soil moisture data for one depth layer since June 2014.

In addition, the quality flags of all soil moisture datasets of station "WSMN-5" and "WSMN-6" were reprocessed because the saturation point for both stations was updated.

The datasets of all stations of the French network "SMOSMANIA" are updated with one year of additional data and are now available until end of 2015.


We would like to thank Jean-Christophe Calvet for providing the updated datasets.

In addition to the soil texture information from the Harmonized World Soil Database (HWSD), from now on the following additional metadata are available for each ISMN station: the land cover class, extracted from the ESA CCI Landcover Classification, and the climate class, based on the Koeppen-Geiger Climate Classification.

We added these static variables to the station specific "..._static_variables.csv" file, which is attached to every zip download of ISMN data.

For the integration of the new datasets, columns were added to the file and a seperate header was added to provide more detailed information about the datasets.

We uploaded an improved version of the data portal. All known bugs were fixed and some improvements were implemented. The advanced download option was also edited to be more user friendly. There, you can run your own SQL queries on the ISMN database and download the result table.

Please leave a comment in the ISMN forum at the corresponding discussion or open a new discussion in the category Portal Issues if you discover any disfunction.

Nine new stations were added to the network 'PBO_H2O'.

All nine stations are located in the USA, 'CSCI SCGN' (csci), 'GNPS SCGN' (gnps), 'IMPS SCGN' (imps), 'LASTCHANCE' (p094), 'ROSASCYN' (p175), 'LAKHENSHAW' (p482) and 'COXCOMBMTN' (p511) in California, 'FOUNTGREEN' (p109) in Utah and 'HORSHEAVEN' (p448) in Washington.

'COXCOMBMTN' is providing soil moisture data since 2011, 'LAKHENSHAW',  'HORSHEAVEN', 'FOUNTGREEN' and 'IMPS SCGN' since 2012 and 'ROSASCYN', 'LASTCHANCE', 'CSCI SCGN' and 'GNPS SCGN' since 2013.

The datasets of the network DAHRA in Senegal were reprocessed and extended by one year until the end of 2015. We want to thank Torbern Tagesson for the effort during the process and for providing the data.

Air temperature and soil temperature of the station "Brush Creek" were reprocessed because of an inconsistency in the original datasets. In addition, all datasets of the station "Brush Creek" were updated until the end of 2015.

The quality flag 'U' was changed to 'G' in accordance with the CEOP Data Flag Description. Since the meaning of the 'U' flag 'unchecked' was not intuitively clear,  the description of the 'G' flag 'good' is more appropriate as all observations formerly flagged with 'U' went through all ISMN quality control procedures without an identification of any suspicious event.

Please adapt your routines accordingly.

Twenty-two new stations were added to the network SNOTEL. They are all located in the United States, 13 in Nevada, 3 in Wyoming, 3 in Utah, 1 in Idaho, 1 in Colorado and 1 in Arizona. Like the other stations of SNOTEL, they will be update in near real time.

There is a new category in the ISMN forum called "Announcements", where you can have a look at forthcoming events or announce one yourself. We already created entries about two very interesting workshops later this year and will continue to report about events that are forwarded to us.

Air temperature measurements were added to the stations "SAA111", "SAA112" and "SAA120", and are now available since September 2012 and June 2014, respectively.

We added a new category to the ISMN forum called "Soil Moisture Jobs". Here you can look up or post open positions in the field of soil moisture (at large in-situ, remote sensing, modelling). We will add job offerings that are forwarded to us but also invite other registered ISMN users to post their offerings. There are already a few job offers online. The forum is not meant for applications.

Six new stations were added to the network 'PBO_H2O'. All six stations are located in the USA, 'SPRECKLESS' (498), 'ANTIMONYFL' (p568), 'BUTTERBRED' (p569) and 'BLINDSPRIN' (p653) in California, 'TUBA_CITY' (p008) in Arizona, and the station 'MIDDLEGATE' (p068) is located in Nevada. 'BLINDSPRIN', 'BUTTERBRED', 'TUBA_CITY' and 'MIDDLEGATE' are providing soil moisture data since 2011, 'ANTIMONYFL' since January 2012 and 'SPRECKLESS' since October 2015.

The datasets of the new network iRON (Roaring Fork Observation Network) in Colorado, USA, are now available. The network consists of 6 stations, one station in Gleenwood Springs, Colorado, and 5 stations around Aspen, Colorado. Each station measures soil moisture in three depths. Additionally, some of the stations are measuring air temperature, soil temperature and precipitation.

We would like to thank Elise Osenga for providing the data and her support during implementation.

The datasets of the network LAB-net were reprocessed. In addition, the datasets have been extended and are now available until January 2016. The network consists of one station, the "Oromo Calibration Site", which is located in Chile.

We want to thank Cristian Mattar for providing the data and his support during the implementation.

Date:  September 21, 2016 - September 22, 2016

Location:  New York City, NY (Hotel TBD)

This workshop is a continuation of the first two soil moisture validation and application workshops held at the European Space Agency in Frascati, Italy, in 2013 and at the Royal Netherlands Academy of Arts and Sciences, in Amsterdam, the Netherlands, in 2014. The objective of this workshop series is to discuss and reconcile methodological advances in the validation and application of global satellite soil moisture data. The workshop is unique in that it brings together satellite soil moisture users and developers to focus on both the derivation and exploration of soil moisture data from both passive and active microwave satellite missions (SMAP, SMOS, ASCAT, AMSR-2, Sentinel-1, and other legacy missions).

The workshop is open to all. There are no fees for attendance but you must register. If you wish to make a presentation you must submit an abstract with your registration. Abstracts will be evaluated for inclusion as either oral or poster presentations.

More info and abstract submission can be found at: https://smap.jpl.nasa.gov/events/46/3rd-satellite-soil-moisture-validation-and-application-workshop-new-york-ny/

Please note that this workshop will follow a SMAP Cal/Val Workshop September 19-20, 2016 that will be held in Manhattan and is open to all that are interested in SMAP. Information on that workshop can be found at: http://smap.jpl.nasa.gov/events/45/

Following up on the outcome of the surveys directed to the ISMN users and data providers, where both sides expressed their wish of enhanced information exchange, we implemented an online forum at https://board.geo.tuwien.ac.at/ismn/. After logging in at the main site (https://ismn.geo.tuwien.ac.at/) by using your ISMN user name and password you are able to add new comments and discussions, share your experiences on datasets, follow specific threads and receive notifications if new discussions are started within certain categories. We are also happy to receive your comments and suggestions concerning our interactive map, the data download service or the forum itself.

We would like to thank Hyunglok Kim for his support during the implementation.

The new network "RSMN" is now available. Currently, it consists of 19 stations homogeneously distributed over Romania, Europe. The network is managed by the Romanian National Meteorological Administration and is part of the ASSIMO project, which aims among others, to create a framework for the validation and evaluation of actual and future satellite microwave soil moisture derived products.

Datasets are currently available for the time span between April 2014 and August 2015 and will be updated continuously.

There are now 7 additional stations available for the network COSMOS. One new station is located in Australia and Alaska, respectively, two are in South Africa, and three in the United States.

Three additional stations ("SAA120", "SOD130" and "SOD140") are now available for the Finnish network "FMI". Also, the station "MAWS" was renamed into "SODAWS". 

In addition, the datasets of all stations were updated until August 2015.

The datasets of all stations of the French network 'SMOSMANIA' were reprocessed by the data provider as an enhanced calibration method was applied to the soil moisture measurements. The datasets are also extended by one year of additional data and are now available until 2015-01-01. We would like to thank Jean-Christophe Calvet for providing the updated datasets. 

The Korean network 'HYU_CHEONGMICHEON' was dismantled thus there won't be any further datasets published. We would like to thank Prof. Minha Choi, Yoomi Hur and Seingjae Han for their contribution to the ISMN.

Both stations of the German network MOL-RAO are updated with five years of additional data and provide now data until the end of 2013. We would like to thank Udo Rummel for providing the new datasets.

The datasets of the station 1 and 2 of the network WSMN in Wales, Great Britian, are updated and now available until February 2015. Furthermore, one new station 'WSMN_7' was added to the network and is providing data since June 2014. Six soil moisture and soil temperature sensors are placed at 10 cm depth spaced a few meters apart. More details can be found here. We would like to thank Gareth Ireland for his support and for providing the data.

The datasets for the network HOBE are now available until the end of 2013. For the stations 1.01, 1.03, 1.04, 1.05, 2.01, 2.10, 2.11 and 3.06 additional datasets at the organic top soil layer were added. These measurements are especially calibrated for organic material and are indicated by the sensor 'Decagon 5TE_C'. The position of stations 2.06 and 2.08 changed and are therefore renamed into 2.06b and 20.8b. We would like to thank Simone Bircher for providing the data.

The datasets of 20 stations of the Spanish network "REMEDHUS" are updated and now available until 2015-01-01. Please note that station 'Guarena' (M13) has been dismantled. We would like to thank José Martínez-Fernández for providing the updated datasets.

All datasets of station 'PoriII' of the Finnish network 'GTK' have been reprocessed because some erroneous measurements were identified. We recommend to download these datasets again and apologize to all users. 

The datasets of the first Chilean network 'LAB-net' are available. Currently the network consists of one station, but new stations will be added in the future. For 'Oromo' station, which is located in the South of Chile, soil moisture measurements in two different depths are available as well as soil temperature, air temperature and precipitation. Observations started in autumn 2014 and will be updated on a weekly basis. We would like to thank Cristian Mattar for granting access to the data.

The new network ORACLE, located in France, includes 6 stations. The datasets are available till 2013 and for some stations the datasets reach back to the year 1985. ORACLE is a research observatory, to the east of Paris, for the study of the "Grand Morin" and "Petit Morin" river catchments, and particularly to develop studies on floods, low water periods, water quality and the impact of human activities on the environment. We would like to thank Delaigue Olivier for granting access to the data and his support during the implementation.

Four new stations are now available within the Austrian network "WEGENERNET". Soil moisture at these locations is derived from matric potential measurements obtained by a pF-Meter. Soil moisture values extracted from matric potentail observations are now also available for the other stations of the WEGENERNET network, starting in 2007 until the sensors were replaced by soil moisture probes in October 2013.

All datasets of the SOILSCAPE network were reprocessed by the data provider, because a new calibration curve was applied to the soil moisture measurements. Currently the spike detection and noise filtering which is usually provided by the SOILSCAPE team is undergoing some maintenance and is therefore off. As soon as the quality control procedure from the data providers is available again, a notification will be posted in this news section.

Four additional stations are now available within the WSMN Network in Wales, Great Britain. While two stations provide soil moisture and soil temperature measurements since May 2013, the same variables are available for the other two stations from September 2011 until January 2014.

We would like to thank George Petropoulos and Gareth Ireland for sharing their data.

Eleven stations of the network "SOILSCAPE" located in the United States were removed. All affected stations are of the 200 series ('"node2xx"). These stations are currently in a test phase and will be added again when the test phase is finished.

The new DAHRA network consists of one station in Senegal. It is managed by the Department of Geography and Geology of the University of Copenhagen. It was installed for studying ecosystem properties and validating remote sensing data products. Continuous measurements of land surface fluxes and state during the rainy season are available from 2002-07-04 to 2014-01-01. We would like to thank Torbern Tagesson and Rasmus Fensholt for sending the data and the permission to make it public.

The SWEX_Poland datasets are not being updated any longer. We thank Boguslaw Usowicz, Jerzy Ucowicz, and Wojciech Skierucha for their support to the ISMN.

Please be aware that the depths of the soil moisture measurements of all stations of the network PBO_H2O were accidentally set to 0-0.5 m and now corrected to 0-0.05 m. We apologize to all users for this inconsistency.

Four new stations are now available within the network PBO_H2O. They are located in New Mexico in the United States, Colombia in South America and the Dominican Republic. The measurements of these stations start in 2011 and will be updated in near real time. In total the network contains 109 stations. New ones will be added in the future.

All stations of the French network "SMOSMANIA" are updated with one year of additional data and provide now data until 2014-01-01. Furthermore the erroneous units of soil temperature measurements for some stations during the year 2012 are corrected.

Due to processing issues, some stations of the SMOSMANIA network may contain soil temperature values in false units for the year 2012. We are working on correcting these datasets and apologize to all users.

For the following seven stations of the italian network UMBRIA the data was reprocessed and updated: Cerbara, Ficulle, Monterchi, Petrelle, Pieve S.Stefano, S.Benedetto and Torre Olmo. The reprocessing was done by the data providers to consider the changing range of variability of the soil moisture measurements. The datasets of the stations Cerbara, Petrelle and Torre Olmo are now available until July 2014, of the other stations until November 2013. We would like to thank Luca Brocca and Luca Ciabatta for providing the updated datasets.

WEGENERNET is a high-density network for regional climate research in southeastern Austria. 12 of the over 150 climate stations in total measure soil moisture as one their components, of which 8 stations are currently included in the ISMN. Others will follow soon. For more information on the additional climate stations please have a look at http://www.wegenernet.org/. Wegenernet is coordinated by the Wegener Center of the University of Graz. In the future, the datasets will be updated in near real time. We would like to thank Gottfried Kirchengast and Jürgen Fuchsberger for preparing and sharing their data with us.

Four new stations are now available within the network ARM. They are located in Kansas and Oklahoma in the United States. The measurements of these stations start in 2011 and will be updated in near real time.

The datasets of all 5 stations of the network "TERENO" are updated, but the station Schoeneseiffen provides no soil moisture anymore. Furthermore  for all parameters of this network the "original" quality flags which are set by the provider are available for the download to complement the flags generated by the ISMN automated quality control procedures. The dataset are now available from 2013-04-01 up to 2014-10-04.

The number of stations of the network PBO_H2O which is located in the United states was increased by 8. Most of the data of the added stations are available from 2007 onwards.

There are 33 new stations available for the network SCAN which is located in the United States. The datasets of these stations start in 2004 onwards. The data will be updated in near real time.

The network HYDROL-NET_PERUGIA now consists of two stations. The station WEEF, that already existed, was renamed as WEEF 1. The new station is WEEF 2. The soil moisture sensors of these stations are very close, so the values for precipitation, soil temperature and air temperature of station WEEF 1 are also valid for station WEEF 2. Both of the new datasets contain the year 2013. We would like to thank Alessia Flammini for granting access to the data.

There are now 47 new stations available for the network SNOTEL. The datasets of the new stations are available since 2012 and will be updated in near real time as well.

There won't be any further datasets published for the network METEROBS. We would like to thank Diodato Nazzareno for providing the available data of 2011 and 2012.

There are now 24 stations instead of one available for the FMI network in Finland. Most of the datasets start in 2011 and are ongoing. The data is updated in near real time. We would like to thank Tiina Parkkinen and Kimmo Rautiainen for providing the data.

New datasets for 18 stations of the network REMEDHUS are now ready to download. The new data is for the whole year 2013. The soils of the stations H09 and M13 were flooded during a long period, so they were discarded for this year.

The PBO_H2O network consists of 98 stations located in the USA. In comparison to other networks the soil moisture data is measured using GPS reflections. The datasets, which are updated in near real time, are available from 2007 onwards. We would like to thank Kristine M. Larson for providing the data and for the support during the implementation.

There are new stations available for the network COSMOS. The data sets of these station start in February 2013 or later. There are now stations all around the world and not just in the USA. The data is in near real time.

New datasets for the two stations Tonzi Ranch and Vaira Ranch of the FLUXNET network have been added. The new data is available for 2011 and 2012.

The SOILSCAPE Network consists of 167 stations which are spread over the United States and updated on a daily basis. The work on this network is being carried out at the University of Southern California, University of Michigan and the Massachusetts Institute of Technology. The data sets are available from 2011-08-03 onwards but the starting date varies per station. We would like to thank Mahta Moghaddam, Agnelo Silva and Dan Clewley from University of Southern California for granting access to the data sets as well as for supporting during the implementation.

The WSMN network is located in Wales, Great Britain, and consists of two stations. The datasets are collected by the Aberystwyth University and are available from 2013-07-11 to 2014-07-01. We would like to thank Dr. George Petropoulos for granting access to the datasets.

The datasets of the station E1 of the network ARM were reprocessed. The reason was a reprocessing of the data by the provider and affects the data from 05-09-1995 to 14-10-2009.

Due to database writing issues, some data sets downloaded between September 2013 and February 2014 may contain false time stamps. To our knowledge the following stations from the SNOTEL network are affected: Culebra 2, Slumgullion, Phantom Valley, and Myrtle Creek. However, we cannot guarantee that other stations/network haven't been affected either, and therefore recommend to replace all data downloaded in this period with those currently online, also for the many good reasons below.

After we had discovered that the old data server wasn't able to catch up any longer with the large processing requirements, we decided to move the International Soil Moisture Network to a new high performance data server. At first sight not much has changed. Only if you look carefully you'll notice that the data portal now has a new URL: https://www.geo.tuwien.ac.at/insitu/data_viewer/

As a pleasant side effect, you'll notice that viewing and downloading data has become much faster.

Beside the quality flags computed during the ISMN processing, we now also pass on the quality flags provided by the contributing networks, whenever available. We think that these can provide additional valuable information when flagging for spurious observations. The "original" flags are stored in a separate column in the download file.

All ISMN observations are now being flagged according to new sophisticated quality control procedures. 27 different flags are used to indicate spurious observations and their causes. The data are being checked for geophysical plausibility using thresholds and ancillary data from in-situ measurements and models. Furthermore, spurious observations like outliers and breaks are detected using spectrum-based approaches. More information on the flag definitions can be found on http://ismn.geo.tuwien.ac.at/data-access/quality-flags/. For a detailed explanation of the various quality checks we refer to Dorigo et al.(2013). Notice that some of the flags can only be computed when the ancillary data become available. For this reason, for the most recent observations these flags can be missing and will be computed as soon as the ancillary data become available.
