×K1. Evapotranspiration in a changing climate

As a key component in water, energy, and carbon cycles, evapotranspiration (ET) affects the climate and ecosystem via a wide range of feedbacks acting on air temperature, humidity, and precipitation. An accurate estimation of ET is therefore a requirement, but it is challenging both in situ and remotely. Since 1800s when John Dalton published the pioneer work on evaporation, remarkable achievements have been made by the community in understanding ET process at varying spatiotemporal scales. However, critical ET-based science and application questions still exist from local to global scales because of limitations in our observation and modeling skills. This session will provide a valuable opportunity to address the ET scientific topics in coordination with efforts in different regions of the world, trying to synthesize results at the global scale.

We invite papers covering, but not limited to, the following topics:

1. Advanced techniques (ground observations and remote sensing) for better determination of ET and its components at multiple scales
2. Responses and feedbacks of ET to climate change and anthropogenic activities
3. Evaporation/sublimation from certain under-studied surfaces including leaf, water body, and snow
4. ET process in hot-spot regions like Tibetan Plateau, Arctic, Amazon, and certain irrigated agricultural areas
5. Employing high-resolution ET product for improved hydrological and/or climate modeling in poorly-gauged regions of the world.

It is great honor for us to chair this session, and your contributions will make this session excellent. We look forward to hearing your insights and experiences in the field of ET-based science and application.
