Version Summary
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- Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover;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 Day_CMG_Confidence_Index variable has been replaced with Day_CMG_Clear_Index.
Overview
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 MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG, Version 61 as an alternative.

General Questions & FAQs
For the snow cover and sea ice products, users can use MODIS Collections 6 and 6.1 together.
Data products from VIIRS are created to be similar to MODIS data products to ensure the continuity needed for the development of snow and sea ice climate records beyond the life expectancy of MODIS. The temporal resolution and spatial extent are identical in MODIS and VIIRS.
The lag time between observations and availability of MODIS products is only a few days. Lag time may be extended due to satellite maneuvers and extra quality assurance required for the geolocation data after the maneuver.

The Normalized Difference Snow Index (NDSI) snow cover is an index that is related to the presence of snow in a pixel and is a more accurate description of snow detection as compared to Fractional Snow Cover (FSC). Snow typically has very high visible (VIS) reflectance and very low reflectan
