MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 2
The MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status Version 2 product is a global record of the daily freeze/thaw (FT) status of the landscape derived from satellite observations of radiometric brightness temperatures. Two FT records are provided: a Scanning Multichannel Microwave Radiometer (SMMR) and Special Sensor Microwave/Imager (SSM/I) record for the years 1979 to 2010; and an Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) record for the years 2002 to 2011.
Note: These data are considered provisional pending a review by the MEaSUREs program. Once the data have been reviewed, this statement will be removed from this documentation.
Version 2 Summary
Changes for this Version 2 release include: an extended FT record enabled by overlapping SMMR and SSM/I brightness temperature time series; a new FT record derived from AMSR-E; refined data Quality Assessment (QA) annual maps; new format options (GeoTIFF with an ESRI projection file); and quick-look GIF browse images.
