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/MYD09GA surface reflectance composites.
