Abstract

Methods to estimate and generate free-surface evaporation E_p and potential evapotranspiration E_t monthly time series are presented. Results are applied to the Quabbin and Wachusett water-supply reservoirs, which serve the Boston metropolitan area, and the Connecticut and Ware River basin watersheds, using historic (1950–80) climate data from several NOAA stations located in New England. The E_p and E_t time series are perturbed using climate-change scenarios of several general circulation models (GCMs) to investigate the sensitivity of both time series to doubled atmospheric CO₂; E_p and E_t are also perturbed by +2°C and +4°C monthly temperature rises. The sensitivity of E_t to a potential climate-change-induced vegetation-canopy resistance is also examined.
