Physically Constrained Fusion of Sentinel-1 and ERA5-Land for Daily 500-m Snow-Depth Retrieval Across Northern Hemisphere Mountains

Quantifying the spatiotemporal distribution of mountain snowpack is critical for hydrology, as it represents a vital freshwater resource for over a billion people. While C-band synthetic aperture radar (SAR) from Sentinel-1 provides high-resolution estimates over mountains, its use for daily snow monitoring is hindered...
