Parameter-elevation Regressions on Independent Slopes Model (PRISM)

Developed at Oregon State University, PRISM is a unique knowledge-based system that uses point measurements of precipitation, temperature, and other climatic factors to produce continuous, digital grid estimates of monthly, yearly, and event-based climatic parameters. PRISM is a knowledge-based system developed primarily to interpolate climate elements in physiographically complex landscapes. Continuously updated, this unique analytical tool incorporates point data, a digital elevation model, and expert knowledge of complex climatic extremes, including rain shadows, coastal effects, and temperature inversions. PRISM data sets are recognized world-wide as the highest-quality spatial climate data sets currently available. PRISM is the USDA official climatological data.
