Data set update: MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status

The MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 4 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to include data for 2017. This data set, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains two global records of the daily freeze/thaw (F/T) status of the landscape. The primary record is derived from radiometric brightness temperatures acquired between 1979 and 2017 by three passive microwave sensors: the Scanning Multichannel Microwave Radiometer (SMMR), the Special Sensor Microwave/Imager (SSM/I), and the Special Sensor Microwave Imager/Sounder (SSMIS). A second, synergistic record is available for the years 2002 to 2017 derived from observations acquired by the Advanced Microwave Scanning Radiometer – Earth Observing System (AMSR-E) and the Advanced Microwave Scanning Radiometer 2 (AMSR2).
