Abstract This data set contains spatially gridded average monthly and annual maximum temperature for the climatological period 1981-2010. Distribution of the point measurements to a spatial grid was accomplished using the PRISM model, developed and applied by Chris Daly of the PRISM Climate Group at Oregon State University.

Purpose Display and/or analyses requiring spatially distributed monthly or annual maximum temperature for the climatological period 1981-2010.

Supplemental Information There are many methods of interpolating climate 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 climate 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 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). PRISM is well suited to regions with mountainous terrain, because it incorporates a conceptual framework that addresses the spatial scale and pattern of orographic processes. Grids were modeled on a monthly basis. Annual grids of temperature are produced by averaging the monthly grids, and summing for precipitation.

Data Quality Information

Horizontal Positional Accuracy Report

Report Accuracy of this data set is based on the original specification of the Defense Mapping Agency (DMA) 1 degree digital elevation models (DEM). The stated accuracy of the original DEMs are 130 m circular error with 90% probability.

Quantitative Horizontal Positional Accuracy Assessment

Horizontal Positional Accuracy Value 130
Horizontal Positional Accuracy Explanation The broad DMA production objective for 1-degree DEM's.

Logical Consistency Report All data were based on the same averaging period (1981-2010). Similar quality assurance procedures were used with all input data sets.

Completeness Report Point estimates of precipitation originated from some or all of the following sources: 1) National Weather Service (NWS) Cooperative (COOP) stations, 2) Natural Resources Conservation Service (NRCS) SNOTEL, 3) United States Forest Service (USFS) and Bureau of Land Management (BLM) RAWS Stations, 4) Bureau of Reclemation (AGRIMET) stations, 5) California Data Exchange Center (CDEC) stations, 6) Storage guages, 7) NRCS Snowcourse stations, 8) Other State and local station networks, 9) Estimated station data, 10) Canadian stations, 11) Upper air stations, 12) NWS/Federal Aviation Administration (FAA) Automated surface observation stations (ASOS), and 13) CoCoRaHS (Community Collaborative Rain, Hail, and Snow Network) stations. All COOP station data were subjected to quality control checks by the National Climatic Data Center (NCDC). All COOP, SNOTEL and other data were subjected to further quality control checks by the PRISM Climate Group.
