Data set update: MEaSUREs Polar EASE-Grid 2.0 Daily 6 km Land Freeze/Thaw Status from AMSR-E and AMSR2, Version 2
The MEaSUREs Polar EASE-Grid 2.0 Daily 6 km Land Freeze/Thaw Status from AMSR-E and AMSR2, Version 2 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 daily GeoTIFF files from 2002 to 2020 have been replaced. Although the data in these files has not been modified, the file metadata has been updated to comply with a new standard for all daily GeoTIFF files, starting with the 2021 temporal coverage extension. The updated GeoTIFF files (and all new daily GeoTIFF files moving forward) can be identified by "v02.1" in their file names.
This data set, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, reports the global, daily freeze/thaw status of the landscape at 6 km resolution on EASE-Grid 2.0 Northern Hemisphere and Southern Hemisphere polar grids. The data are derived from observations acquired by the Japan Aerospace Exploration Agency's (JAXA) Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) and the Advanced Microwave Scanning Radiometer 2 (AMSR2).
