The regional evapotranspiration of the Amazon

David Werth, Roni Avissar

Research output: Contribution to journalConference articlepeer-review


Two methods that were used to produce the annual cycle of evapotranspiration (ET) at the scale of the Amazon were evaluated. The methods exhibited different annual cycles, with a large difference among the various techniques obtained in the winter dry seasons. The two major controls on ET are the available energy at the surface and the way that vegetation regulates transpiration through its stomata. As the methods studied varied in the way they incorporated this regulation, the resulting ET cycles varied as well.
