It features 32-day composites of orthorectified scenes using top-of-atmosphere reflectance. The dataset uses the Normalized Difference Snow Index (NDSI), computed from Green and Mid-IR bands to identify snow with a range of -1.0 to 1.0, with a pixel size of 30 meters. Data is public domain, and usage must cite the USGS as the source.\n"]]
