It uses Level L1T orthorectified scenes with top-of-atmosphere reflectance to create annual composites. The Normalized Difference Snow Index (NDSI), derived from Green and Mid-IR bands with values from -1.0 to 1.0, is used to identify snow. The dataset is complete and public domain. It's recommended to use Collection 1-based datasets, and cite the USGS when using this data.\n"]]
