MODIS Terra Daily NDSI [deprecated]

  • This MODIS dataset provides daily global Normalized Difference Snow Index (NDSI) values derived from MOD09GA surface reflectance composites.

  • NDSI, ranging from -1.0 to 1.0, helps identify snow cover based on reflectance differences in the visible and mid-infrared spectrum.

  • This dataset is deprecated; consider using the updated MODIS/MOD09GA_006_NDSI dataset for current snow cover information.

  • Data is available from February 24, 2000, to March 30, 2017, and is freely accessible for research, education, and non-profit use.

  • The dataset is provided by Google and has no restrictions on subsequent use, sale, or redistribution.

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.
