Willmott and Rowe have created a terrestrial water budget data archive on a 1-degree grid. They identified 13332 global stations with complete records and created 30-year (1950-1979) climatological means for each month of the year for air temperature, precipitation, evaporation, soil moisture, and snow cover. These monthly climatological means were then interpolated to the 1-degree gridpoints. This data set contains the 1-degree gridpoint data and the individual station data.

DSS has created a GRIB version of the gridpoint data for users who prefer the GRIB format.
