Evapotranspiration (ET) is a fundamental process that influences a wide range of applications across scientific disciplines such as ecology, agriculture and meteorology. In ecology, ET is critical in regulating the water balance of ecosystems, affecting plant growth, carbon uptake, and nutrient cycling. Understanding ET patterns and dynamics is essential for predicting ecosystem response to changes in environmental conditions, such as climate or land use change. In agriculture, ET is critical for estimating crop water requirements and scheduling irrigation, helping to optimize crop yield and reduce water use in water limited regions. It can also indicate drought conditions, providing insights into water availability and potential crop stress. Ultimately, ET is critical for understanding the Earth’s energy balance and the role of the water cycle in regulating the climate system. By accurately modeling and monitoring ET, we can improve our ability to understand climate change impacts on water resources and ecosystems, while increasing the resiliency of these systems. Considering this, and in keeping with this year’s AMS theme of “Living in a Changing Environment”, we are seeking submissions related to novel approaches focusing on ET field to remote sensing monitoring and modeling. We encourage interdisciplinary ET studies aiming to explain, mitigate, and/or prevent disruptions or changes in ecosystems, agriculture, drought, or climate.
