Short summary
In this study we evaluate the performances of observation-based and climate model-based evapotranspiration estimations and project future changes for evapotranspiration in Australia. Our results show that climate models can provide reasonably accurate estimations, compared to observation-based estimations. This study offers new insights into future water loss and demand changes in Australia with implications for agriculture production, water security, and environmental management.
