The regional evapotranspiration of the Amazon

David Werth, Roni Avissar

Research output: Contribution to journalConference articlepeer-review


Two independent methods that are used to produce the annual cycle of evapotranspiration (ET) at the scale of the Amazon are discussed. The methods are net radiation method in which S88 depicts high annual ET and weak annual cycle, and global climate modeling method in which the GISS model experiences a wintertime minimum in ET. Both are similar in that they are based on the energy and water balance equations at the land surface. However, the representation of the water transfer at the surface is different in these methods. Both the methods exhibit different annual cycles that led to a large difference among the various techniques obtained in the winter dry season.
