PRISM (Parameter-elevation Regressions on Independent Slopes Model) was first developed by Dr. The PRISM Climate Group is part of the Northwest Alliance for Computational Science and Engineering (NACSE), within the College of Engineering. In the United States, high-resolution spatial weather and climate data sets are developed on an ongoing basis by Oregon State University’s PRISM Climate Group.

These grids typically describe conditions over a monthly or daily time step, and offer estimates where weather stations do not exist. Spatial weather and climate data, usually in the form of continuous grids of pixels, are often key inputs to decision support systems and tools that require environmental data.
