Delivery of new Suomi National Polar-orbiting Partnership (Suomi NPP) satellite observations will cease on November 2, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.Suomi NPP data announcement
Description
This data set reports monthly average snow cover in 0.05 degree (approx. 5 km) resolution Climate Modeling Grid (CMG) cells. Monthly averages are computed from daily snow cover observations in the MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG (MOD10C1) data set.
As of August 2023, this data set is retired and no longer available for download. We recommend using <a href="https://nsidc.org/data/mod10cm/versions/61">MODIS/Terra Snow Cover Monthly 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Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover.
Citation is critically important for dataset documentation and discovery. This dataset is openly shared, without restriction, in accordance with the EOSDIS Data Use and Citation Guidance.
