Session 4A Advances in Estimating Evaporation, Evaporative Demand, and Associated Applications Part II

Tuesday, 8 January 2013: 3:30 PM-5:30 PM
Room 10B (Austin Convention Center)
Host: 27th Conference on Hydrology
Martha C. Anderson, USDA/ARS, Hydrology and Remote Sensing Lab, Beltsville, MD

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 might include: • estimating ET from various perspectives: remote sensing platforms, ground-based point observations and parameterizations, plant-based experimentation, and water budgets; operational ET estimation; land surface-atmosphere feedbacks; future remote sensing missions and needs for ET; Eo as an input to operational LSMs to derive ET, schedule crop irrigation, and as a metric of hydroclimatic trends and variability.
