Future Climate Models
NEW!– CliMond is a wonderful site built by modelers for other modelers supplying free climate data products consisting of interpolated surfaces at 10′ and 30′ for recent historic climate and relevant future climate scenarios. The data is available as monthly climate data, 35 Bioclim variables, in CLIMEX format, and as the Köppen-Geiger climate classification scheme. A publication describes their collaborative project and datasets:
Kriticos, D.J., Webber, B.L., Leriche, A., Ota, N., Macadam, I., Bathols, J. & Scott, J.K. (2012) CliMond: global high resolution historical and future scenario climate surfaces for bioclimatic modelling. Methods in Ecology and Evolution 3: 53-64. DOI: 10.1111/j.2041-210X.2011.00134.x
IPCC Data Distribution Centre – The data center for the Intergovernmental Panel for Climate Change, providing observational data, general circulation model datasets, socio-economic scenarios and other environmental scenarios. Both general introductory material and primary literature references are provided.
Statistically Downscaled WCRP CMIP3 Climate Projections – An archive of downscaled translations of 112 climate projections developed through the World Climate Research Programme’s Coupled Model Intercomparison Phase 3 (CMIP3) effort, representing 16 CMIP3 models and 3 greenhouse gas emissions scenarios. Projection-specific attributes include:
— surface air temperature and precipitation
— 1950-2099 time coverage on a monthly time step
— conterminous United States spatial coverage at 1/8° spatial resolution, including portions of Canada and Mexico.

10-minute Future Climate Grids (U Wisconsin-Madison) CMIP3 models downscaled with CRU CL 2.0 modern model, available in several emission scenarios from the 4th IPCC Assessment as Arc ASCII grids.
The easiest to use portal may be CIAT website for downscaled GCMs where the Decision and Policy Analysis (DAPA) program has posted statistically downscaled future climate models (IPCC v.4) for 4 scenarios in decadal averages from 2020 through 2080. These have been processed using the same spline methodology as Worldclim and are available from 30 second to 10 minute resolutions in grid or ascii for Tmean, Tmin, Tmax, Precip and Bioclimate variables.
Current Climate Models (last century)
Worldclim — global interpolated climate dataset available up to 1 km resolution in *bil (generic) or ESRI grid format. See: Hijmans, R.J., S.E. Cameron, J.L. Parra, P.G. Jones and A. Jarvis, 2005. Very high resolution interpolated climate surfaces for global land areas. International Journal of Climatology 25: 1965-1978. Also available for future and past climate models now.
PRISM Group Climate Data – PRISM (Parameter-elevation Regressions on Independent Slopes Model) climate mapping system, developed by Dr. Christopher Daly, is constantly being updated and has historic and current climate data sets. The new PRISM data sets are 30 arc second resolution.
Spectral Modeling Downscaling Results for Western North America – Hourly, daily, monthly and yearly averages for regional and continental US. (10 km resolution)
Earth System Grid – DOE’s main data portal for national labs and research centers for public access to climate data products, e.g. CCSM, CCSM POP (Parallel Ocean Process version), CSIM, CLM, PCM, POP. FTP access requires registration.
Paleoclimate Reconstructions, NOAA Paleoclimatology Program – Both global and regional reconstructions of past climate of varying resolution and time periods for Air Temperature, Precipitation, Hydroclimate, Circulation, Vegetation, Sea Surface Temperature, and Global Ice Coverage among others.
Paleoclimate Modelling Intercomparison Project Phase II (PMIP 2) – Focusing on model-model and model-data comparisons of paleo-climate and environmental conditions, this site is a good resource to find current projects and publications including datasets.

Goddard Institute for Space Studies (GISS) focuses on climate and space research; the website has both climate-related data, maps, animations, and software tools for visualizing datasets.
