Estimating Downward Shortwave Radiation over Complex Terrain: Synergizing Sentinel-2 Imagery and Topographic Data via Physics-Guided XGBoost

Downward shortwave radiation (DSR) varies strongly across mountain slopes, and products designed for horizontal surfaces may not resolve this variability. We estimated slope-parallel DSR at eight Saihanba sites using Sentinel-2 imagery, topography, atmospheric inputs, and BRDF-in...
