MODIS/Aqua 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/Aqua Snow Cover 8-Day L3 Global 500m Grid (MYD10A2) data set. Persistent cloud cover is also reported.
There is a more recent version of these data.
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- Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover;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;
- 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.
