   The data are appropriate for global change related assessment of 
   land-atmosphere water, energy and carbon cycle interactions. Although 
   extensive quality checking has been completed, these are research data and the 
   user is responsible for their own quality checking and should be aware that 
   spurious values may exist. The authors hold no responsibly for conclusions 
   drawn from spurious data. We appreciate constructive and well-documented 
   feedback to help make these data more useful. Questions and feedback should be 
   sent to Lucas Jones (lucas@ntsg.umt.edu).

Group: Summary

   Notice to Data Users: The documentation for this data set was provided solely 
   by the Principal Investigator(s) and was not further developed, thoroughly 
   reviewed, or edited by NSIDC. Thus, support for this data set may be limited.

   This data set contains satellite-retrieved geophysical parameter files 
   generated from the Advanced Microwave Scanning Radiometer - Earth Observing 
   System (AMSR-E) instrument on the National Aeronautics and Space 
   Administration (NASA) Aqua satellite. The daily parameter retrievals extend 
   from 19 June 2002 to 27 September 2011 and include daily air temperature 
   minima and maxima (ta) at approximately 2 m in height; fractional cover of 
   open water on land (fw); vegetation canopy microwave transmittance (tc); 
   surface soil moisture (mv) at ≤ 2 cm soil depth; and integrated water 
   vapor content of the intervening atmosphere (V) for the total column. The 
   global retrievals were derived over land for non-precipitating, non-snow, and 
   non-ice covered conditions. The primary input data were daily AMSR-E dual 
   polarized multi-frequency, ascending and descending overpass brightness 
   temperature data. The total volume for this data set is approximately seven 
   gigabytes. Data are provided in zipped binary files and are available via FTP.
