Assessing Regional Climate Models (RCMs) Ensemble-Driven Reference Evapotranspiration over Spain
The present work applies a novel methodology of combining multiple Regional Climate Models (RCMs) (or ensemble) that are based on the seasonal and annual variability of temperatures over Spain, which allows for the quantification and reduction of uncertainty in the projections of temperature based-p...
