MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 4
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of 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 satellite-based 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).
There is a more recent version of these data.
- Extended F/T record to 2017;
- F/T domain expanded to all land areas affected by seasonal freezing, including urban, snow-ice dominant, open water body dominant, and barren land;
- Added a modified seasonal threshold algorithm (MSTA) and pixel-wise, annual MSTA calibration using daily surface air temperature records;
- Added bit flags to identify cells (and days) with missing/interpolated Tb, large open water bodies, complex terrain, and large precipitation events;
