MODIS/Aqua Snow Cover 8-Day L3 Global 500m Grid, Version 6

This data set reports the maximum snow cover extent during an eight-day period in 1200 km x 1200 km tiles. Tiles are generated by compositing 500 m observations from the MODIS/Aqua Snow Cover Daily L3 Global 500m Grid (MYD10A1) data set. Bit flags are also provided that report the eight-day snow/no-snow chronology for each 500 m cell.

Version Summary:

Changes for Version 6 include:

  • Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover.;
  • Aqua MODIS band 6 data have been restored to scientific quality using a Quantitative Image Restoration (QIR) technique. Aqua now uses the same snow detection algorithm as Terra;

Geographic Coverage

In August, NSIDC removed all MODIS Version 6 browse images due to errors. The science granules were unaffected. We have begun replacing the deleted images with corrected versions, starting with forward processing from 10 November 2016 onward. Historic browse images will be replaced from the beginning of each mission and moving forward. In the meantime, browse data are available for MOD10_L2/MYD10_L2 and MOD29/MYD29 through NASA's Earthdata Search.
