MODIS/Terra Snow Cover 8-Day L3 Global 0.05Deg CMG, Version 6

This data set reports the maximum percentage of snow-covered land during an eight-day period in 0.05 degree (approx. 5 km) resolution Climate Modeling Grid (CMG) cells. Percentages are computed from snow cover observations in the MODIS/Terra Snow Cover 8-Day L3 Global 500m Grid (MOD10A2) data set. Persistent cloud cover is also reported.

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  • Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover;
  • The Eight_Day_CMG_Confidence_Index variable has been replaced with Eight_Day_CMG_Clear_Index.

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.
