Sentinel-1 SAR and Temporal Lag Soil Moisture Estimation at Instrumented Field Sites: A Stacked Ensemble Approach

Field-scale soil moisture (SM) estimation from Sentinel-1 C-band SAR alone is challenged by vegetation, roughness, and spatial heterogeneity. This study proposes a Stacked Additive Boosting-based Model (SABM) that combines Sentinel-1 SAR, Sentinel-2 optical, and ancillary geophysical features with temporal lag SM featu...
