Summary: Fires can be destructive or healthy for a landscape—often both. Fires have grown larger and more destructive in recent years, though, thanks to human activity, climate change, and a host of other factors. Satellite data helps us to map and monitor fire activity, but the study of post-fire plant life using remote sensing data goes further than fire mapping. On this episode of Eyes on Earth, we hear from Dr. Helen Poulos, who used data from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, (ECOSTRESS), to study Arizona Pine Oak forest 5-7 years after severe fire. Dr. Poulos and her collaborators at Northern Arizona University and the University of Maine at Farmington learned that post-fire shrublands had surprisingly high rates of water use. ECOSTRESS data are available through NASA’s Land Processes Distributed Active Archive Center or LP DAAC, which is located at EROS.
