Precipitation Maps

in PDF Format

The precipitation maps were produced from Daymet data. Daymet is a model that generates DAILY surfaces of temperature, precipitation, humidity, and radiation over large regions of complex terrain. Daymet was been developed at the University of Montana, NTSG Lab, to fulfill the need for fine resolution, daily meteorological and climatological data necessary for plant growth model inputs.

Using a digital elevation model and daily observations of minimum and maximum temperatures and precipitation from ground-based meteorological stations, an 18 year daily data set (1980 - 1997) of temperature, precipitation, humidity and radiation has been produced as a continuous surface at a 1 km resolution. A wide range of summary and point daily data over the conterminous United States are now available. For more information, see the Daymet Homepage.
