The Climate Data Access and Analysis System (CDAAS) is a user-friendly web-based portal to access and analyze different global climate models, gridded observation datasets, and downscaled regional climate model products.

CDAAS is designed to serve both the lay end-user to easily generate powerful visualizations as well as experts for detailed analysis. Users with access to the system can select the region of interest and get the respective data sets in various formats for further analysis.

The tool handles data from three different sources and is categorized primarily based on the horizontal grid resolution of the models. Which includes CMIP5 Global Climate Models (GCMs), Coordinated Regional downscaling experiments (CORDEX), and NEX Nasa datasets.
