Data for MODIS Collection 6.1 are being processed from the beginning of the MODIS data record. As such, the temporal coverage will be incomplete until processing catches up to the present day. To access the complete temporal coverage of this specific data set in Collection 6.0, add “/versions/6" to the end of the URL. MODIS Collection 6.0 data sets will be processed continuously through spring 2022, after which forward processing will cease.

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.

There is a more recent version of these data.

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  • Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover;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

What is NDSI snow cover and how does it compare to FSC?
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 reflectance in... read more
Missing and delayed MODIS data
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 MODAPS... read more
Can I merge MODIS data from Collections 6 and 6.1 for a given data set?
In short, yes. For the snow cover and sea ice products, users can use Collections 6 and 6.1 together. Users should be aware that there were minor changes in calibration for C6.1 that could potentially induce some differences, however the impacts of these changes on the snow and sea ice products... read more
