Abstract:

This data set contains spatially gridded average monthly and annual minimum temperature for the climatological period 1971-2000. Distribution of the point measurements to a spatial grid was accomplished using the PRISM model, developed and applied by Chris Daly of OSU PRISM Group.

Purpose:

Display and/or analyses requiring spatially distributed monthly or annual minimum temperature for the climatological period 1971-2000.

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 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 influence. temperature was modeled monthly. Annual grids of temperature are produced by averaging the monthly grids. A Gaussian filter was applied to increase the resolution of the grids from the base resolution 30 arc-seconds (~800 m) to 15 arc-seconds (~400 m). This filter is a modification of the Barnes filter (Barnes, 1964), originally adapted by Dr. Stephen Esbensen of Oregon State University, and later modified for use here by Wayne P.Gibson, also of Oregon State University.

Data_Quality_Information:

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 temperature 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 Group.
