NEX-DCP30: Ensemble Stats for NASA Earth Exchange Downscaled Climate Projections (NASA/NEX-DCP30_ENSEMBLE_STATS)
Version 1
The NASA NEX-DCP30 dataset is comprised of downscaled climate scenarios
for the conterminous United States that are derived from the General
Circulation Model (GCM) runs conducted under the Coupled Model
Intercomparison Project Phase 5 (CMIP5, see Taylor et al. 2012)
and across the four greenhouse gas emissions scenarios known as
Representative Concentration Pathways (RCPs, see Meinshausen et al. 2011)
developed for the Fifth Assessment Report of the Intergovernmental Panel
on Climate Change (IPCC AR5). The purpose of these datasets is to provide
a set of high resolution, bias-corrected climate change projections that
can be used to evaluate climate change impacts on processes that are
sensitive to finer-scale climate gradients and the effects of local
topography on climate conditions.
The dataset contains monthly projections covering the periods from 1950
through 2005 (Retrospective Run) and from 2006 to 2099 (Prospective Run).
It includes ensemble statistics calculated for each RCP from all model
runs available for the pr, tasmin, and tasmax bands.
NEX-DCP30 was prepared by the Climate Analytics Group and NASA Ames
Research Center using the NASA Earth Exchange, and distributed by the NASA
Center for Climate Simulation (NCCS).
