The International Soil Moisture Network is an international cooperation to establish and maintain a global in-situ soil moisture database. This database is an essential means of the geoscientific community for validating and improving global satellite observations and land surface models.
Soil moisture, which is the water stored in the upper soil layer, is a crucial parameter for a large number of applications, including numerical weather prediction, flood forecasting, agricultural drought assessment, water resources management, greenhouse gas accounting, civil protection, and epidemiological modeling of water borne diseases. Therefore, the societal benefits of the International Soil Moisture Network are expected to be large.
This international initiative is coordinated by the Global Energy and Water Exchanges Project (GEWEX) in cooperation with the Group of Earth Observation (GEO) and the Committee on Earth Observation Satellites (CEOS). The International Soil Moisture Network has been made possible through the voluntary contributions of scientists and networks from around the world. The International Soil Moisture Network is operated in cooperation with the Global Soil Moisture Databank of the Rutgers University.
