   Description: 
      Abstract:
         The MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 3 
         data set is a global record of the daily freeze/thaw (F/T) status of the 
         landscape derived from satellite observations of radiometric brightness 
         temperatures. Two F/T records are provided: one derived from Scanning 
         Multichannel Microwave Radiometer (SMMR), Special Sensor Microwave/Imager 
         (SSM/I), and Special Sensor Microwave Imager/Sounder (SSMIS) data for the 
         years 1979 to 2012; and a second derived from Advanced Microwave Scanning 
         Radiometer - Earth Observing System (AMSR-E) data 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.
