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/Aqua Snow Cover Daily L3 Global 500m Grid (MYD10A1) data set. Cloud cover percentages are also provided.
NOTE: Reverb will be decommissioned in the coming months and replaced with Earthdata Search. All links to Reverb will be removed at that time.
MODIS/Aqua Snow Cover Daily L3 Global 0.05Deg CMG, Version 6
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- Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover;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.
- 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;
