#AAAR2022. @kjmayer4. (disclosure: I was involved in this study)
- Cited study showing in 2020 over 25 million Americans (8%) experienced >100 ug/m3 of PM2.5.
- #CASAChem Experiments looked at the impact of long range smoke impacts.

- #CASAChem Experiments looked at the impact of long range smoke impacts.
1/
- Examined 1) fresh smoke, 2) fresh smoke plus ozone, 3) aged smoke.
- Ozone addition to fresh smoke did not change the particle composition or sized distribution significantly indoors.
2/
- Ozone addition to fresh smoke did not change the particle composition or sized distribution significantly indoors.
2/
- Aged smoke was smoke that sat in chamber for a couple hours prior to injection into the house.
- Ozone in addition to aged smoke shows change in particle chemical concentrations over time.
3/
- Ozone in addition to aged smoke shows change in particle chemical concentrations over time.
3/
- Evidence of SOA formation over time indoors with the aged smoke. New particle counts after ozone injection. Behaving similarly to outside smoke airplane measurements.
Why was there nucleation instead of condensation onto surfaces?
