Atmospheric pressure has a negligible role in evapotranspiration compared to factors like radiation intensity, atmospheric dew point, temperature, wind, and soil moisture.
Evapotranspiration is the combined process of evaporation (water from surfaces like soil and water bodies) and transpiration (water from plants) into the atmosphere. It is primarily driven by the energy available (radiation), the difference in water vapor concentration between the surface and the atmosphere (humidity/dew point), and the movement of air (wind).
