Abstract
This raster dataset incorporates a conceptual framework that uniquely addresses the spatial scale and pattern of orographic precipitation. The original PRISM dataset covered the United States. This is a California-only version subsetted from the original data set and converted to California Teale Albers NAD83 using bilinear interpolation by the California Department of Fish and Game (CDFG) at 2.5 arc-minutes resolution (approximately 4km). Care should be taken in estimating precipitation values at any single point on the map. Precipitation estimated for each grid cell is an average over the entire area of that cell; thus, point precipitation can be estimated at a spatial precision no better than half the resolution of a cell. Accuracy of this data set is based on the original specification of the Defense Mapping Agency (DMA) 1 degree digital elevation models (DEMs). The stated accuracy of the original DEMs is 130m circular error with 90% probability.
Purpose
The Parameter-elevation Regressions on Independent Slopes Model (PRISM) Climate Group works on a range of projects, some of which support the development of spatial climate datasets. These PRISM datasets provide estimates of the basic climate element of precipitation (ppt), or the Daily total precipitation averaged over a month for both rain and melted snow. These datasets are modeled with PRISM using a digital elevation model (DEM) as the predictor grid and provide baselines describing average monthly precipitation between 1961 and 1990 to be used for display and/or analyses requiring spatially distributed monthly or annual precipitation.
Supplemental Information
There are many methods of interpolating precipitation from monitoring stations to grid points. Some provide estimates of acceptable accuracy in flat terrain, but few have been able to adequately explain the extreme, complex variations in precipitation that occur in mountainous regions. Significant progress in this area has been achieved through the development of PRISM (Parameter-elevation Regressions on Independent Slopes Model). PRISM is an analytical model that uses point data and a digital elevation model (DEM) to generate gridded estimates of monthly and annual precipitation (as well as other climatic parameters). PRISM is well suited to regions with mountainous terrain, because it incorporates a conceptual framework that addresses the spatial scale and pattern of orographic precipitation.

Lineage
Process Step
Description
It is beyond the scope of this metadata to document the processes involved in generating spatially gridded precipitation using the PRISM model. However, the processes are documented in numerous conference proceedings and journal articles. The references can be found online at URL:http://www.ocs.orst.edu/prism/prism_new.html.
Process Step
Description
Downloaded data and metadata from ( http://www.ocs.oregonstate.edu/prism/index.phtml ). Converted to ESRI grid format. Calculated value attribute by dividing original PRISM value by 100 (was originally mm * 100). Added/calculated mm and inches attributes. Changed datum reference from WGS72 to NAD83 (did not physically shift the data, just changed the definition for easier compatibility with other NAD83 datasets - minor difference between WGS72 and NAD83 given the scale of the data).
