Non-frozen period
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.

The time range for this dataset is January 01, 1979 (00:33 AM) to September 27, 2011 (23:59 PM).

The spatial range for this dataset is -86.72° to 86.72° latitude, and -180.00° to 180.00° longitude. map (center)
