GIS Climate Change Scenarios project is conducted by the NCAR GIS Initiative and intended to serve a community of GIS users interested in climate change. This GIS data portal provides access to free global datasets of climate change scenarios generated for the 4th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) by the Community Climate System Model (CCSM). The datasets can be downloaded in a common GIS format (i.e., shapefiles) or text file format. Currently, our GIS portal distributes a subset of all the data produced by the CCSM. One can view and/or download global monthly mean, 2D atmospheric and land variables from the CCSM component models.

IMPORTANT: To access data, you must register and login.

This website is intended to be complimentary to other climate data distributing centers (e.g., IPCC Data Distribution Centre (DDC), Program for Climate Model Diagnosis and Intercomparison (PCMDI), and the Earth System Grid (ESG). To learn more about IPCC, climate science, modeling and policy, NCAR, CCSM, NCAR GIS Initiative and to see frequently asked questions, visit tabs, links and help documents throughout this website.
