English abstract:
Earth observation and more specifically, spaceborne radar remote sensing, has made much progress towards retrieving Soil Moisture (SM) at different scales. The use of coarse-scale measurements from active or passive microwave sensors for SM retrieval is well established and in operational use. The Copernicus Global Land Service (CGLS) provides daily global SM data, retrieved from Metop-ASCAT scatterometer measurements at 0.1 spatial sampling. The Sentinel-1 satellite mission, launched in 2014 and deploying Synthetic Aperture Radars (SAR), delivers high-resolution radar imagery at the scale of 20 meters. Observations from Sentinel-1 are evaluated for upgrading the SM portfolio of the CGLS. Exploiting the SAR signal at the 20m scale, high-quality SM information at 1km sampling is generated for Europe, with a daily time stamp. The 1km SSM product describes the surface soil moisture (SSM), whereas the SCATSAR-SWI product, a soil water index (SWI), combines input from ASCAT and Sentinel-1 and estimates the soil profile wetness down to 1m depth. Both products are under preparation for operational production and dissemination by the CGLS.
