Evapotranspiration, the process of water evaporating from land and plants releasing water vapor, is crucial for understanding water cycles. Scientists developed a method using satellite data to estimate evapotranspiration rates based on vegetation and temperature. By analyzing NDVI (Normalized Difference Vegetation Indices) and temperature data, they created a model to predict evapotranspiration levels in different regions. This approach helps us better understand how vegetation and temperature impact water evaporation, which is essential for managing water resources effectively.
