Dear ISMN community,
we are in the middle of transferring the ISMN to our new host, the International Centre for Water Research and Global Change at the German Federal Institute of Hydrology (BfG).
Users that register between 22-11-2022, 2pm (UTC) and 31-11-2022 can’t be transferred and will have to reregister. We apologise for any inconveniences and appreciate your understanding!
Your ISMN teams in Vienna and Germany!


Welcome to the International Soil Moisture Network

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 for validating and improving global satellite products, and land surface, climate, and hydrological models.
Soil moisture, which is the water stored in the upper soil layer, is a crucial variable in a wide variety of processes and 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 large.
The International Soil Moisture Network is a combined effort of the Global Energy and Water Exchanges Project (GEWEX), the Committee on Earth Observation Satellites (CEOS), the Global Climate Observing System - Terrestrial Observation Panel for Climate (GCOS-TOPC), the Group of Earth Observation (GEO), and the Global Terrestrial Network on Hydrology (GTN-H). The International Soil Moisture Network has been made possible through financial support of the Earth Observation Programme of the European Space Agency (ESA) and the many voluntary contributions of scientists and networks from around the world.
