U.S. Department of Agriculture – Natural Resources Conservation Service
Percent of average annual precipitation for each of 12 months raster layers. Also provided are raster average minimum and maximum temperature datasets from derived average annual temperature according to a model using point temperature data for the 30-year period of 1981-2010. PRISM is an analytical model that uses point data and an underlying grid such as a digital elevation model (DEM) or a 30 yr climatological average (e.g. 1981- 2010 average) to generate gridded estimates of monthly and annual precipitation and temperature (as well as other climatic parameters). 800m spacing.
