Real Time Evapotranspiration Monitoring and Forecasting Based on Alabama Mesonet.

Evapotranspiration is a critical component and important process in the water cycle as it is responsible for 15% of the atmosphere's water vapor. In this study we monitored real-time evapotranspiration at 24 weather stations in Alabama using standard penman-monteith method. Direct evapotranspiration measurement from eddy covariance will be used to validate the monitored results. Past meteorological data is used to predict and forecast the potential evapotranspiration at the 24 stations. The monitored and forecast evapotranspiration are helpful for farmers to make irrigation schedule and water management.
