Montana Average Daily Minimum Temperature, 1971-2000

Data Provider PRISM Group, Oregon Climate Service, Oregon State University
Date 1971 - 2000
Content Type Downloadable Data
Abstract These data are estimates of average daily minimum temperature, in degrees Fahrenheit, for the climatological period 1971-2000. In other words, each value represents the average of every daily low temperature over the 30 year period.Parameter-elevation Regressions on Independent Slopes Model (PRISM) derived raster data are the underlying data set from which the data were created. PRISM is an analytical model that uses point data and a digital elevation model (DEM) to generate gridded estimates of annual, monthly and event-based climatic parameters. For further information, the online PRISM homepage can be found at http://www.ocs.orst.edu/prism/.The data are available as an ESRI GridASCII export file, in latitude/longitude coordinates with a horizontal resolution of 0.00833 degrees, for the entire United States from the Oregon Climate Service web site. The data for Montana is available in Montana State Plane Coordinates, resampled to a resolution of 600 meters, in either GeoTIFF format or as a shapefile with polygons representing 29 temperature ranges.
Purpose
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 a digital elevation model (DEM) 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.
