MODIS Terra Daily NDSI [deprecated]

  • This dataset provides the Normalized Difference Snow Index (NDSI), used to identify snow based on its reflectance properties.

  • The NDSI is calculated using the Green and Mid-IR bands and ranges from -1.0 to 1.0.

  • This dataset is generated from MODIS/MOD09GA surface reflectance composites.

  • This dataset is deprecated and has been superseded by MODIS/MOD09GA_006_NDSI.

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/MOD09GA surface reflectance composites.
