Estimating reference evapotranspiration with the FAO Penman–Monteith equation using daily weather forecast messages

Real-time irrigation management and water resources allocation need real-time prediction of daily reference evapotranspiration (ETo). Thus, adopting the FAO Penman–Monteith (FAO-PM) equation as the standard for ETo estimation, an attempt was made to predict daily ETo using the public weather forecast messages available in China. These involve the cloudiness conditions, daily maximum and minimum temperature, and wind speed scales. An analytical...
