I have a strong interest in evapotranspiration measurement and theory (see this basic USGS page about ET, where I also got the image left). My particular interest is in (i) evaporation from inundated water and (ii) hillslope processes.

See this GEWEX article (p.5) from March 2019 entitled "Current Challenges in Evapotranspiration Determination" I've co-authored about ET.

Also see my 2019 paper in JGR Atmospheres where I compare model-derived and GLEAM evaporation rates for predicting drought areas in the Horn of Africa. link.

In October 2019 we organised a GHP cross-cutting workshop Determining Evaporation led by Prof. Joan Cuxart in Sydney, Australia. See here. I presented a talk Evapotranspiration in the JULES land surface model.

The 2nd GEWEX Evapotranspiration workshop will be hosted by Univ. Wageningen online on 10-12th February 2021.

Prof. Henk de Bruin visited CEH Wallingford on 8th March 2019 and gave a wide-ranging talk entitled Evapo(transpi)ration: How to model it? How to measure it? A critical review of the state of the art and a call for novel research. The seminar attracted several senior hydrologists and micro-meteorologists from pre-CEH days. CEH article in The Grapevine is here and the slides and audio are here (including the energy balance closure blues!).
