The NARCCAP dataset contains high-resolution climate change scenario simulation output from multiple RCMs (regional climate models) nested within multiple AOGCMs (atmosphere-ocean general circulation models) for 30-year current and future periods.
The RCMs are run at 50-km spatial resolution over a domain convering the conterminous United States and most of Canada; results are recorded at 3-hourly intervals. The driving AOGCMs are forced with the A2 SRES emissions scenario in the future period. This dataset also include output from two timeslice experiments and a set of 25-year RCM simulations driven with NCEP-2 reanalysis data. These simulation results are useful for impacts analysis, further downscaling experiments, and analysis of model performancy and uncertainty in regional scale projections of future climate.
