We estimated Amazon ET using a catchment-balance approach and compared our results with remote sensing and reanalysis products, climate models from #CMIP5 and #CMIP6, and flux tower data. 2/7
Most products struggled to capture key features of Amazon ET, like the strong seasonal cycle, and the fact that Amazon ET is mostly limited by available solar energy. 3/7
There was little agreement in the direction of ET trends over the past 20 years. 4/7
The future of Amazon ET is entwined with the fate of the Amazon rainforest, but uncertainty remains over the direction of ET trends over the next century. 5/7
Until climate models are better able to capture historical patterns of ET and the processes that control it, attempts to understand future changes in the Amazon water cycle will be severely hampered. 6/7
