Description
Abstract Spatially distributed monthly and annual average maximum/minimum/dew point temperature. Each file represents 1 month of 1 year for the period January 1997 to the present. Distribution of the point measurements to a spatial grid was accomplished using the PRISM model, developed by Christopher Daly, Director, The PRISM Climate Group, Oregon State University. Care should be taken in estimating temperature values at any single point on the map. Temperature estimated for each grid cell is an average over the entire area of that cell; thus, point temperature can be estimated at a spatial precision no better than half the resolution of a cell. For example, the temperature data were distributed at a resolution of approximately 4km. Therefore, point temperature can be estimated at a spatial precision no better than 2km. However, the overall distribution of temperature features is thought to be accurate. For further information, the online PRISM homepage can be found at URL:http://prism.oregonstate.edu.
Purpose Display and/or analyses requiring spatially distributed monthly or annual average maximum/minimum/dew point temperature for the period 1997-Present
Supplemental Information There are many methods of interpolating temperature 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 temperature 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 average daily maximum/minimum/dew point temperatures (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 temperature. Temperature was modeled monthly. For this application, PRISM was parameterized to use existing 1971-2000 mean daily maximum/minimum/dew point temperature grids as the predictor grids in the interpolation. The PRISM weighting functions for distance, "elevation" (now the 1971-2000 climatology), topographic facet, atmospheric layer, orographic effectiveness, and coastal proximity were all retained. This allowed observed deviations from normal to be interpolated with sensitivity to physiographic factors. An annual average was produced by averaging the monthly grids.

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 (1971-2000). 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, 0) Canadian stations, 10) Upper air stations, and 11) NWS/Federal Aviation Administration (FAA) Automated surface observation stations (ASOS). 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.
