Description

This data set reports the percentage of snow-covered land in 0.05° (approx. 5 km) resolution Climate Modeling Grid (CMG) cells. Percentages are computed from snow cover observations in the MODIS/Terra Snow Cover Daily L3 Global 500m Grid (MOD10A1) data set. Cloud cover percentages are also provided.

As of August 2023, this data set is retired and no longer available for download. We recommend using <a href="https://nsidc.org/data/mod10c1/versions/61">MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG, Version 61</a> as an alternative.

Version Description

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  • Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover;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