Climate Change Datasets

NCAR’s Community Climate System Model (CCSM3) was one of the global climate model included in the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC). NCAR’s GIS program provides GIS-compatible user access to CCSM3 AR4 global (1.4 degree or ~155 km) and downscaled (4.5 km) continental U.S. simulations. Follow the links below to access data as shapefiles, textfiles, KML files, WMS, WCS or download a map.

Web Maps

NCAR GIS Program have started to display climate and weather data through interactive web maps.  These web maps use ESRI ArcGIS Server and the power of ArcGIS Online in order to animate time aware data.
