Simultaneous Subpixel Retrieval of Lake Ice and Snow From MODIS Data: Resolving Spectral Ambiguity via a Physics-Informed Framework
Lake ice and snow cover on the Tibetan Plateau play a critical role in regulating lake-surface radiative, thermodynamic, and hydrological processes, yet accurate monitoring remains challenging at moderate spatial resolutions. Over frozen lakes, widely used snow products (e.g., MOD10A1) frequently misclassify lake ice a...
