Evapotranspiration is the combined process of evaporation of water from the Earth’s surface and the transpiration of water from plants. It plays a critical role in the hydrological cycle, influencing water availability, soil moisture, and climate. Understanding evapotranspiration is essential for water resource management, agriculture, and climate modeling.
