Description:Seminar Abstract:\nThe increased intensity of wildfires in the 
 American West has halted the progress made in improving air quality. For e
 xample\, surface ozone and PM2.5 decreased for many years across the West\
 , but these trends have stopped or have even reversed. Another major emerg
 ing issue is the occurrence of urban fires as happened in Colorado (Marsha
 ll Fire)\, Hawaii (Lahaina Fire) and California () in just the last few ye
 ars. In my presentation\, I will summarize our group’s work on wildfires
 . We made measurements of air pollutants after the Marshall Fire both insi
 de smoke-impacted homes as well as outside from a mobile laboratory. One i
 ssue with urban fires is that the burnt structures contain many man-made m
 aterials. We have studied the emissions from the burning of such materials
  in the lab\, and used the results in the interpretation of our field meas
 urements. Finally\, I will discuss how satellite data hold information on 
 the phase of a wildfire (flaming vs. smoldering) and how this information 
 can be used in improved ozone forecasts.\nSpeaker Bio:\n\nJoost de Gouw is
  a Professor and Chair of the Chemistry Department of the University of Co
 lorado Boulder\, and a Fellow in the Cooperative Institute for Research in
  Environmental Sciences (CIRES). He earned a PhD in Physics from the Unive
 rsity of Utrecht in 1994 and worked from 2001 through 2017 as a Research S
 cientist with the NOAA Earth System Research Laboratory. Joost de Gouw’s
  research interests include the sources and chemical reactions of organic 
 compounds and related air pollutants in the atmosphere\, and how these pro
 cesses impact air quality and climate. His research group uses mass spectr
 ometry\, gas chromatography and data from satellite remote sensing instrum
 ents in their work. Joost de Gouw was a co-recipient of the Colorado Gover
 nor’s Award for High-Impact Research in 2012\, 2014 and 2022\, was a Web
  of Science Highly Cited Researcher in 2017 and 2018\, and was elected a F
 ellow of the American Geophysical Union in 2020.\n 4:00 pm
