The 2nd Global Evapotranspiration Symposium: Advances, Challenges, and Future Needs in Measurements, Modeling, and Applications


Event Date

The Penn Stater Hotel and Conference Center; The Pennsylvania State University, University Park, Pennsylvania October 23-27, 2023

In the 21st century, increasing population growth, demand for energy consumption, agricultural expansion, groundwater extraction, and global climate change are placing enormous pressure on limited water resources resulting in environmental and social crises in many parts of the world. Evapotranspiration (ET) is a major component of the hydrologic cycle that directly or indirectly links to water resources availability and use, water quality, ecosystem productivity, food and fiber production, and Earth’s energy balance and climate system. Evapotranspiration science is central to understanding the consequences of environmental, ecosystem and agricultural systems change and human adaptation to global change. Measuring and modeling ET at multiple scales is not only resource intensive, but also technically and practically challenging. Under broad climatic controls, ET is influenced by parameters that vary across multiple scales – from site-specific variables such as soil, topography, vegetation type, soil moisture status, snow, agronomic and soil management practices, and microclimatic conditions, to the spatial heterogeneity of land use and management at landscape scales, and ultimately to regional and/or global climate/weather patterns. ET processes at the smaller and medium scales (e.g., leaf to landscape) have important controls/feedback to the regional and global climate systems through complex interactions among Earth’s atmospheric, hydrological, and biogeochemical cycles. Emerging innovative methods, models, tools, and technologies offer promises in advancing both our ability to accurately quantify ET and our understanding of plant water use at different scales; such knowledge will be critical for developing effective management strategies to cope with emerging water resources and related challenges.
