Climate projections and assessments

A statistical downscaling method (bias-correction and spatial disaggregation: BCSD) is applied to general circulation models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5) to generate high-resolution downscaled precipitation, maximum temperature, and minimum temperature estimates under historical and three future emission scenarios over the Northeastern United States.
