About this site

Welcome to NCAR's GIS Program Climate Change Scenarios GIS data portal. This portal is intended to serve a community of GIS users interested in climate change. The free datasets of climate change projections can be downloaded as a shapefile, a text file, or as an image. Many 2D variables from modeled projected climate are available for the atmosphere and land surface. These climate change projections were generated by the NCAR Community Climate System Model, or CCSM, for the 4th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

To access data, you must register, login and accept data disclaimer. Please read data disclaimer carefully.

Thank you for visiting GIS Climate Change Scenarios website. This GIS portal is complimentary to other IPCC data distributing portals (e.g., Program for Climate Model Diagnosis and Intercomparison (PCMDI), and the Earth System Grid (ESG)), where complete data archive is available in common atmospheric data formats.
