Description
The Normalized Difference Snow Index is used to identify snow, based on its characteristically higher reflectance in the visible portion of the spectrum compared to the mid-IR. NDSI is computed using the Green and Mid-IR bands, and has a range of -1.0 to 1.0. See Riggs et al. (1994) for details. This product is generated from the MODIS/006/MOD09GA surface reflectance composites.
