NASA Earth Exchange Downscaled Climate Projections 30 Arcseconds CMIP6

Abstract

Abstract We describe the latest version of the NASA Earth eXchange Downscaled Climate Projections 30 arcseconds (NEX-DCP30-CMIP6). The archive contains downscaled historical and future projections for 1950–2100 based on output from Phase 6 of the Climate Model Intercomparison Project (CMIP6). The downscaled products were produced using a daily variant of the monthly bias correction/spatial disaggregation (BCSD) method and are at 30-arcsecond horizontal resolution. Four variables (maximum temperature, minimum temperature, precipitation, and vapour pressure) from five CMIP6 experiments (historical, and the four Tier 1 scenarios: SSP1.2-6, SSP2.4-5, SSP3.7-0, and SSP5.8-5) are provided as available from thirty global climate models. The downscaled data cover the coterminous United States (CONUS), extending from approximately 24-50 degrees North and 235–294 degrees East.
