Data set update: MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 5
The MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 5 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated through 31 December 2021. The F/T status is now provided as a single Earth System Data Record derived from SMMR, SSM/I, and SSMIS from 1979 to 2020, and AMSR2 from 2021 onwards. The separate AMSR-E–AMSR2 data record (2002 - 2020) has been discontinued. The metadata for GeoTIFF and HDF files have been enhanced, and GIFs have been added for AM and PM F/T statuses. The inaccurate SMMR pixel counts in annual QA files have been corrected. The file names have been updated with "v05.1".
This data set, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides the freeze/thaw (F/T) status of the landscape, in the morning and afternoon, at 25 km on the original EASE-Grid.
