How can we measure Evapotranspiration from Space? with Gilles Boulet

Can we measure evapotranspiration from space? And when a satellite produces a map of crop water use, how certain are those numbers? Dr. Gilles Boulet joins host Veena Srinivasan for a deep dive into one of the most important and difficult-to-measure components of the hydrological cycle: evapotranspiration. Evapotranspiration, or ET, combines evaporation from soil with transpiration through vegetation. In many semi-arid landscapes, it accounts for most of the water leaving the land surface. Ho...
