EVAPOTRANSPIRATION EVALUATION FOR NORTHEASTERN BRAZIL WITH REANALYSIS AND REMOTE SENSING DATA

Abstract
Abstract - Evapotranspiration (ET) is the second most important variable of the hydrological cycle, second only to precipitation, and influences numerous processes in the atmosphere. Thus, it is interesting to study the changes of this variable in Northeast Brazil (NEB). The ETP trends in the NEB between 1961-2020 will be analyzed from high resolution 0.1° x 0.1º grid data, constituting more than 2000 points in the NEB. A cluster analysis will be employed to see how many homogeneous groups the NEB can be divided into. The trends will be checked using the Mann-Kendall method. These are specific objectives to assist the main objective of this research which is to evaluate the performance of two sources of ET data, one provided by reanalysis and the other by remote sensing. The reanalysis source will be the ET from the ERA5-Land project and the remote sensing source from the MODGroETa project, both at the same spatial resolution of the observed grid, 0.1° x 0.1º.
