Description

This data set reports the location of snow cover based on the Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections. The NDSI is derived from radiance data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Terra satellite.

As of August 2023, this data set is retired and no longer available for download. We recommend using <a href="https://nsidc.org/data/mod10_l2/versions/61">MODIS/Terra Snow Cover 5-Min L2 Swath 500m, Version 61</a> as an alternative.

Version Description

Changes for Version 6 include:
  • Fractional Snow Cover has been replaced by Normalized Difference Snow Index (NDSI) snow cover. Fractional Snow Cover is no longer calculated;
  • The binary Snow-Covered Area (SCA) map has been discontinued;
  • Data screens designed to reduce snow detection errors have been revised and several new screens have been added;
  • Data screen results, including snow detection reversals and detections with increased uncertainty, are provided in a new QA bit flag;
  • Basic pixel-level QA uses new criteria to indicate the overall quality of algorithm result.
