Estimation of surface soil moisture from Sentinel-1 Synthetic Aperture Radar imagery using machine learning method
Surface soil moisture (SM) is a crucial variable representing the water content in soil at the topmost soil layer. Accurate data of SM are essential for many applications such as drought monitoring, vegetation modelling, weather forecasting, and agriculture management. Over the past decades, microwave remote sensing has been employed to estimate SM at large scales, with the Sentinel-1 satellite mi
