H34D:
Evapotranspiration, Evaporative Demand, and Droughts: From Empirical Shortcuts to Process-Based Understanding III


Session ID#: 10535

Session Description:
We invite contributions in the broad areas of: evaporation and transpiration modeling, prediction and observation across scales; process based approaches to determining drivers for past and future trends in evaporative demand; and conceptual frameworks for characterization and linking meteorological, agricultural and hydrological droughts through their impacts on plants and crops, soil moisture, and stream flows. Applications of new sensing technology and observational methods for quantification of evapotranspiration are particularly encouraged.
