Improving the downscaling of climate model for impacts assessments


We improved downscaling of general circulation model (GCM) data for climate change impacts assessments in the Lake Champlain Basin as part of the VT Experimental Program to Stimulate Competitive Research (EPSCoR).  This effort investigated the potential for using high-resolution topographic data to further downscale existing bias-corrected and statistically downscaled GCM simulations of temperature and precipitation. We found large changes in several impact variables of relevance to the region, including hot days, cold days, maple syrup production, and cooling degree days.

This project evaluated local projected changes in climate across, as well as drives high-resolution hydrologic and ecological models for, the Lake Champlain Basin.
