Advances in the estimation of evapotranspiration (ET) and atmospheric evaporative demand (Eo) are made across a broad range of scales and techniques, from in situ observations to remote sensing and modeling. Specific topics for this session may include, but are not limited to, (1) estimating ET from various perspectives: remote sensing platforms, ground-based point observations and parameterizations, plant-based experimentation, and water budgets; (2) operational ET estimation; (3) land surface–atmosphere feedbacks; (4) future remote sensing missions and needs for ET; (5) Eo as an input to operational LSMs to derive ET and schedule crop irrigation, and as a metric of hydroclimatic trends and variability. New methods are emerging to more robustly partition total ET between evaporative and transpirative fluxes from both a modeling and a measurement perspective. We encourage papers with a focus on information conveyed by E and T, as well as ET. This year, recognizing that transpiration is regulated through vegetation hydrodynamics, we are particularly seeking submissions relating to both experimental and theoretical work linking plant hydrodynamics, ecology, hydrology, and meteorology. Understanding and simulating these hydraulic behaviors of vegetation and their outcomes, in terms of water and carbon flux, is key to improving land surface and hydrologic models. Advances in remote sensing of water content and new databases compiling extensive monitoring records of site- and plant-level water flux and hydraulic trait data are poised for incorporation into such models through an emerging body of vegetation hydrodynamics modeling frameworks.
