This National Science Foundation Project Grant of $480,484 supports research to understand drought and post-drought legacy effects in tropical forests. Funded under the Biological Sciences program (CFDA 47.074), the University of California, Los Angeles will leverage a large-scale drought experiment in an Amazon forest in Brazil. Researchers will integrate high-resolution tower-based radar data measuring vegetation water content at finer scales than satellites. This will be compared with plant physiology measurements to infer drought stress responses at tree and forest scales. The August 1, 2022 award also supports training one postdoctoral researcher and two science workshops engaging stakeholders to identify improvements in monitoring and predicting land-atmosphere interactions under drought risk. Outcomes aim to advance scientific understanding of drought impacts on tropical forests from individual trees to ecosystem scales.
