The webinar will give an overview of high-resolution (1 km) satellite soil moisture data sets available at continental to global scale. These data sets are either derived by downscaling coarse resolution data from passive (SMAP, SMOS, AMSR2) and active (ASCAT) microwave sensors using optical or Synthetic Aperture Radar (SAR) data, or by deriving the soil moisture data directly from only the SAR data. The presentation will focus on the latter type of products, explaining how soil moisture data can be derived from Sentinel-1 SAR time series, and how these data might be used for monitoring rainfall and irrigation.
