Switch to snow 6.1

[profLewis]

Dear Colleague,

The MODIS Collection 6.1 Snow Cover and Sea Ice data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), were released in the last year and data reprocessing is now complete. The full temporal coverage, from February 2000 for MODIS/Terra data sets and July 2002 for MODIS/Aqua data sets to present, is available. Collection 6.1, also known as Version 61, is largely compatible with Collection 6/Version 6, but NSIDC urges users to switch to the newer Collection 6.1 as Collection 6 will stop forward processing in mid 2022.

Access to the data sets and their documentation is provided at https://nsidc.org/data/modis/data_summaries
