Evapotranspiration Seasonality over Tropical Ecosystems in Mato Grosso, Brazil

Brazilian tropical ecosystems in the state of Mato Grosso have experienced significant land use and cover changes during past few decades due to deforestation wildfire. These can directly affect mass energy exchange near surface and, consequently, evapotranspiration (ET). Characterization seasonal patterns ET help understanding how these function with a changing climate. The goal this study was characterize temporal (seasonal-to-decadal) spatial over using remotely sensed products. Ecosystems areas limited no flux towers be performed remote sensing products such as NASA’s MOD16A2 (MOD16 ET). As accuracy product is unknown, secondary objective evaluate ability MOD16 (ETMODIS) appropriately represent Grosso, Brazil. Actual measured (ETMeasured) eight towers, three Amazon, Cerrado, two Pantanal Grosso. In general, ETMODIS all sites had difference from ETMeasured analyzed periods, moderate strong correlation ETMeasured. variation some similarity climatology higher mid southern parts (Cerrado Pantanal) wet period compared dry period. Amazon patterns, lower season season, minimal insignificant seasons. decreased first second decades, but increased Cerrado same This highlights importance deepening climate change.
