Description
-----------
This ftp location is an official repository for the " 103-Year High-Resolution
Climate Data Set for the Conterminous United States".  This project was
funded by the "NOAA Climate Change and Detection Program".

dem_metadata.txt
        FGDC compliant metadata describing the elevation data file.

us_25m.dem.gz
        Digital elevation model (DEM) data. Same domain as for data
        stored in the decadal directories.
