Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections

This data archive is meant to provide access to climate and hydrologic projections at spatial and temporal scales relevant to some of the watershed and basin-scale decisions facing water and natural resource managers and planners dealing with climate change.

The archive contains fine spatial-resolution translations of 112 contemporary climate projections over the contiguous U.S. and parts of Canada and Mexico. The Bureau has applied a process to bias-correct these model results down to 1/8th degree across the U.S. This website describes the data, provides tutorials for downloading and interpreting the data, and enables users to select a subset of the data specific to their needs.

The data projections permit several types of analyses, including:

  • assessment of potential climate change impacts on natural and social systems (e.g., watershed hydrology, ecosystems, water and energy demands).
  • assessment of local to regional climate projection uncertainty.
  • risk-based exploration of planning and policy responses framed by potential climate changes exemplified by these projections.
