NASA Armstrong & JPL Take Flight to Study California's Wildfire Burn Areas

As California experiences one of the worst wildfire seasons on record, NASA is leveraging its resources to help. NASA’s C-20A aircraft took off from its base at NASA's Armstrong Flight Research Center Building 703 in Palmdale, California, carrying the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument developed and operated by NASA's Jet Propulsion Laboratory. Attached to the bottom of the aircraft, the radar is flown repeatedly over an area to measure tiny changes in surface height with extreme accuracy. But the instrument is also highly effective at mapping burn scars, because radar bounces off vegetation in a different way than they do bare, freshly burned ground. What's more, UAVSAR flights over burn areas produce observations that are ten-times higher resolution than satellites, meaning flights can be quickly tasked to target vulnerable areas of burn scars after being identified in satellite images. After vegetation is burned away, sloping hillsides and valleys can become susceptible to mudslides during winter rains, often months later. The researchers intend to produce data products that can be used to identify areas most at risk. ℹ️To learn more visit: https://www.nasa.gov/feature/jpl/nasa... 📲💻Follow us on Instagram, Facebook, & Twitter @NASAArmstrong
