The “Evapotranspiration” product presents global maps showing the monthly forecast of evapotranspiration anomalies for the next six months. These anomalies are represented relative to the historical average, with positive values indicating above-average evapotranspiration and negative values indicating below-average evapotranspiration.
Evapotranspiration is the process by which water is transferred from the Earth’s surface to the atmosphere, involving two stages: the evaporation of water from the soil and plants, and the transpiration of plants. This phenomenon is fundamental to the hydrological cycle and directly influences soil water availability, impacting crop growth and ecosystem health. Understanding these variations is crucial for optimizing water resource management, planning effective irrigation, and assessing agricultural impacts. Additionally, this information helps guide decisions on environmental conservation and climate change adaptation strategies.
