Spatial climate products (digital maps) are available through the link below. These products were developed through a partnership between the NRCS National Water and Climate Center (NWCC) and the PRISM Climate Group at Oregon State University (OSU), developers of PRISM (the Parameter-elevation Regressions on Independent Slopes Model).

This partnership has resulted in the production of the best and, in many cases, the first high-spatial-resolution climate map products for the United States. PRISM is an analytical tool that uses point data, a digital elevation model, and other spatial data sets to generate gridded estimates of monthly, yearly, and event-based climatic parameters, such as precipitation, temperature, snowfall, degree days, and dew point.

All products now available have been thoroughly scrutinized, having passed a strenuous peer-review process in cooperation with state and regional climatologists across the nation. The goal is to deliver the highest quality and most accurate climate maps of the U.S. ever produced.
