NEX-DCP30 HomeNEX-DCP30 data on a very fine 800-m grid that covers the continental United States (CONUS) for a variety of climate change assessments that require higher resolution data.
The full NEX-DCP30 dataset includes 33 climate models and their respective downscaled data for historical (1950-2005) and 21st century simulations under four Representative Concentration Pathways (RCP) emission scenarios developed for AR5. Our application, the NEX-DCP30 Viewer, includes historical and future (2006-2099) climate for RCP4.5 (one of the possible trajectories for greenhouse gas (GHG) emissions in which atmospheric GHG concentrations continue to rise but are capped so as not to exceed a radiative equivalent of 4.5 Wm-2 in 2100) and RCP8.5 (the most aggressive emissions scenario in which GHGs continue to rise unchecked through the end of the century leading to an equivalent radiative forcing of 8.5 Wm-2.)
The NEX-DCP30 Viewer allows the user to visualize projected climate change for any county in the continental United States. To create a manageable number of permutations for the viewer, we have averaged the NEX-DCP30 data into 25-year climatologies that span the 21st century. The viewer provides a number of useful tools for characterizing climate change such as: climographs (plots of monthly averages), histograms that show the distribution or spread of the model simulations, monthly time series spanning 1950-2099, and tables that summarize changes in the quantiles of temperature and precipitation (e.g., extremes). The application also provides access to comprehensive, 3-page PDF summary reports for the CONUS, each states and each county.
A detailed description of the application and its use can be found in the NEX-DCP30 Viewer Tutorial.
