  <Quality>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).</Quality>

  <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 &amp;#8804; 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.  </Summary>
