Ruby author Qian, Yun author Nunes, Ana M. B. author Roads, John O. author Sloan, Lisa C. author Snyder, Mark A. author NSF National Center for Atmospheric Research publisher The North American Regional Climate Change Assessment Program (NARCCAP) is a collection of regional climate model simulations downscaling global simulations from CMIP3 to 50-km resolution over North America. The collection was generated in 2007-2012 with the goal of investigating uncertainties in regional scale projections of future climate and generating climate change scenarios for use in impacts research. NARCCAP comprises a set 12 simulations from 6 RCMs downscaling 4 GCMs using a fractional factorial design, plus 1 simulation from each RCM downscaling the NCEP reanalysis, and 2 global atmosphere-only timeslice experiments. Historical data spans 1971-2000, and future data 2041-2070 using the SRES A2 emissions scenario. It includes more than 3 dozen 2D variables and a half-dozen 3D variables at 3-hourly frequencies, plus a handful of static and daily variables. All data is at 50-km spatial resolution over a domain that covers most of North America and is stored in CF-compliant netCDF files.
