new: first International Soil Moisture Network

International Soil Moisture Network

is now officially online!

At this moment it contains the in-situ soil moisture measurements of three operational networks: OzNet (AUS), REMEDHUS (Spain) and SMOSMANIA (France). The International Soil Moisture Network was initiated by the Global Energy and Water Cycle Experiment (GEWEX) in cooperation with the Group of Earth Observation (GEO) and the Committee on Earth Observation Satellites (CEOS). ESA, through the SMOS mission, is providing the initial funding for this initiative. Data hosting, maintenance and web-based distribution will initially be performed by the Vienna University of Technology (TU Wien). The long term perspective foresees the development from a centralized archive to a distributed archive and a transfer of the tasks of TU Wien to operational organisations active in this field.

The special focus of the International Soil Moisture Network will be to bring all in-situ measurements into a common, volumetric soil moisture unit and to provide extensive data and metadata descriptions according to the prevailing standards. Both campaign data and data measured by fully automated networks are included. Besides soil moisture data measured at different depths, the database also aims at including meteorological variables (e.g. temperature, precipitation) and metadata (e.g. soil porosity, bulk density) that facilitate a better interpretation of the measured soil moisture values.
