Higher temperature increases capacity to hold moisture.
Higher wind speed removes saturated air from the surface.
Lower humidity increases Vapor Pressure Deficit (VPD).
Energy available to convert liquid water to vapor.
Estimated Evapotranspiration ()
4.25 mm/day
Penman-Monteith Factors:
- Energy Term: Radiation drives vaporization.
- Aerodynamic Term: Wind and humidity drive transport.
- Higher Temp + Wind + Radiation = Higher ET
- Higher Humidity = Lower ET
