Viewing the data is possible without registration. To download any data you first need to login or register at the bottom left of this page.
In the following paragraphs the data download and viewing process are explained.
To start the data download/viewing application press the "Data Access" button on the bottom left of this page.
To download data you have to select the networks and the time range from the menu on the left, you can also specify a latitude/longitude range but that's not mandatory. When the selection process is finished press the "Download" button and select the data format in which you want to receive the data. By pressing the "Create File" Button a .zip file with your data is created and a link to it will be provided as soon as it is finished. (Notice: This can take a while depending on the amount of data selected)
Two format types are available (klick for further information):
- Variables stored in separate files (CEOP formatted)
- Variables stored in separate files (Header+values)
Depending on the zoom level the networks or the stations are shown on the map. Clicking on a network (red marker) will show you information about that particular network and a button to zoom to the stations of that network. Clicking on a station (blue marker) will show more information about it and a button to view the data recorded by this station. When clicking the "View Data" button the data that is available, in the date range which is selected in the menu, will be loaded. You can then explore the data by selecting up to 3 variables from the selectors at the bottom of the data viewer. It's also possible to zoom into the data using either the mouse wheel, the buttons at the top or the range selector at the bottom. (Notice: If to much data is selected the data viewing can become slow and the browser may freeze depending on your system specifications. Try to use a modern web browser.)
By clicking the "Advanced Download" button in the menu, a new window/tab opens and you can enter custom SQL queries. The database structure is displayed at the right side of the screen and shows all the available tables and columns. The "Execute" button executes the query and returns a table with the results or an error. If the result is good the "Create File" button will generate a .zip file with your data.
It will be possible to download data automatically using python scripts that will be provided as soon as they are finished and thoroughly tested.
