WebSoil moisture reveals a lot about a place, from which areas of a farm need irrigation to which neighborhoods are likely to flood. Satellites and in-ground sensors provide valuable data on soil moisture, but these methods can be expensive and scarce when it comes to getting detailed information about frequently- changing conditions. WebEstimating soil moisture based on synthetic aperture radar (SAR) data remains challenging due to the influences of vegetation and surface roughness. Here we present an algorithm that simultaneously retrieves soil moisture, surface roughness and vegetation water content by jointly using high-resolution Sentinel-1 SAR and Sentinel-2 multispectral imagery, with …
