Forecasting Reference Evapotranspiration in the Southeastern USA

Estimates of reference evapotranspiration are needed for determining
agricultural water demand, reservoir losses, and driving agricultural and hydrological simulation models. Output from Atmosphere-Ocean General Circulation Models (GCMs) are potentially useful for forecasting reference evapotranspiration, however they often contain significant biases and are typically produced at a scale that is too coarse for local or regional application.

This project sought to evaluate the use of weather and climate models to forecast reference evapotranspiration at a fine-scale resolution (16km/32 km) across the southeastern USA. To date, two journal articles (link) (link) have been pupted in the Journal of Hydrometeorology and another in the Journal of Hydrology (link) on using the Global Forecast System (GFS) and Global Ensemble Forecast System (GEFS) retrospective forecast archives. In addition, a journal article has been published in the Journal of Hydrometeorology (link) evaluating the Climate Forecast System Version 2 (CFSv2) to produce 1-9 month forecasts of reference evapotranspiration.
