Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections

This archive contains high-resolution translations of climate projections for the contiguous United States. Archive content is based on global climate projections from the World Climate Research Programme’s Coupled Model Intercomparison Projects. Phase 3 (CMIP3) and Phase 5 (CMIP5) of these experiments informed the Intergovernmental Panel on Climate Change’s Fourth Assessment Report and Fifth Assessment Report, respectively.

Users can specify a customized data retrieval through the Subset Request form, or access ftp directories containing projection-specific full coverage datasets (variable, space, time) in netcdf data format through the Complete Archives tab.
