Soil Moisture from Metop ASCAT Data at High Latitudes
Several global satellite-derived soil moisture datasets exist to date. They are based on analyses of passive or active microwave data. Resolution is coarse at 25 km, but temporal sampling is very high. A monitoring service for applications at high latitudes is implemented within the European Space A...
