Group: Summary

   This data set contains modeled daily thaw depth and freezing depth for the 
   Arctic terrestrial drainage basin. Thaw and freezing depths were calculated 
   over the study area with a resolution of 25 km x 25 km. Data extend from 
   September 1998 through December 2000. A finite-difference model for 
   one-dimensional heat conduction with phase change calculates daily thaw and 
   freezing depths, based on data of snow water equivalent, soil temperature, 
   soil dry-bulk density, and soil water content. Data are in space-delimited 
   ASCII text format and are available via FTP.
