These small fires are hard to detect via satellites and are not well accounted for in estimates of air quality in the US. We are working to better understand both how much smoke comes from these fires, and what the smoke is made of. 3/3pic.twitter.com/qoRnzpy4Zj
Expert #2: Hi! I’m Steve Brown, the primary investigator for one of the @NOAA Twin Otters (N48RF, the “Chem Otter”) during the FIREX-AQ campaign and a research chemist at @NOAA_ESRL, where I study atmospheric chemistry and regional air quality. 1/2pic.twitter.com/zQCmJp10rx
The Twin Otter is a small aircraft that can study the chemistry of wildfire smoke during day/night. Both sunlight and darkness change the composition of smoke. The Twin Otter can also fly in tight valleys that fill w/smoke overnight and where exposure to people is greatest. 2/2pic.twitter.com/WpFQ6qonOD
Expert #3: Hi! I’m Kelley Barsanti, an associate professor in the Department of Chemical & Environmental Engineering and Center for Environmental Research and Technology at @UCRiverside. My research focuses on developing predictive models for atmos. particles or “aerosols”. 1/2pic.twitter.com/03WWGRFLFo
During the FIREX-AQ campaign, my group is collecting wildfire smoke from the Twin Otter aircraft and Aerodyne mobile lab to identify the gaseous organic compounds in smoke, which allows more accurate modeling of the chemistry in smoke plumes. 2/2
