H-Snow Data Products

This archive contains sample data products generated by the H-Snow daily 10 m snow cover mapping framework, including the dataset and accompanying documentation. The dataset spans the period from 2002 to 2025, with data organized in folders corresponding to each calendar year. Daily data files are named following the yyyy_doy.tif convention, where doy denotes the day of the year. Pixel values within each GeoTIFF range from 0 to 255: 0 represents no-data areas outside the watershed boundary, 85 indicates snow cover, 170 corresponds to snow-free land surfaces, and 255 denotes water pixels. The original dataset has a spatial resolution of 10–20 m. Due to file size upload constraints, the distributed sample data has been resampled to 100 m and compressed. Nevertheless, the products retain substantial spatial detail and are suitable for qualitative analysis.
