Climate Data

Western Regional Climate Center Summaries for Towns in Colorado

This site provides detailed summaries of daily and monthly precipitation and temperature data from 1960 to the present. Summaries are provided in graphical and tabular formats. A great resource!

The NRCS PRISM Climate Mapping Project Dataset for Colorado

PRISM (Parameter-elevation Regressions on Independent Slopes Model) was developed by Dr. Christopher Daly of Oregon State University, and is a hybrid statistical-geographic approach to mapping climate. PRISM uses point measurements of climate data and a digital elevation model (DEM, a digital, gridded version of a topographic map) to generate estimates of annual, monthly and event-based climatic elements. PRISM is not a static system of equations; rather, it is a coordinated set of rules, decisions and calculations designed to mimic the decision-making process an expert climatologist would invoke when creating a climate map. This dataset is provided in Shapefile format and requires GIS software.

NRCS Monthly Preciptitation Data for Colorado

These datasets contain vector and polygon coverages of average monthly and annual precipitation for the climatological period 1961-90. Parameter-elevation Regressions on Independent Slopes Model (PRISM) derived raster data is the underlying data set from which the polygons and vectors were created. Datasets are provided in ascii grid or ArcInfo Export formats and require GIS Software.

The National Climate Data Center

The Center has long served the Nation as a national resource for climate information. NCDC's data is used to address issues that span the breadth of this Nation's interests. As climate knows no boundaries, the NCDC works closely with scientists and researchers world-wide. The Center develops both national and global data sets that have been used by both government and the private sector to maximize the resource provided by our climate and minimize the risks of climate variability and weather extremes. In Colorado the National Climate Data Center Partners with The Colorado Climate Center (below) and the Western Regional Climate Center (also below) to provide a wide variety of weather data.

The Colorado Climate Center

The Colorado Climate Center is part of the Department of Atmospheric Science at Colorado State University. It's goal is to assist the state of Colorado in monitoring climate over time scales of weeks to years. They also recognize that climate involves complex interactions between the atmosphere, the oceans, continental glaciers, and the land. Vegetation processes are an important component of the climate system. This service should contribute to a reduction in the state's vulnerability to climate variability and change.

NOAA-CIRES Climate Diagnostic Center

The National Oceanic & Atmospheric Administration (NOAA) has partnered with the University of Colorado and CIRES to produce this site. The goal of their work is to develop the ability to predict important climate variations on various time scales. Short-term climate variations of interest include major droughts and floods over the continental U.S., and the global anomalies associated with El Niño-Southern Oscillation (ENSO). These events attract great public interest, and often have enormous social and economic consequences. On longer time scales, basic research goals include identifying the causes for decadal to centennial climate variations, and separating natural variability from anthropogenically induced climate changes in order to provide an improved scientific basis for public planning and policy decisions.

Western Regional Climate Center

The mission of the Western Regional Climate Center is to disseminate high quality climate data and information pertaining to the western United States; foster better use of this information in decision-making; conduct applied research related to climate issues; and improve the coordination of climate-related activities at state, regional and national scales.
