In this analysis, a team, led by Art Sedlacek at Brookhaven National Lab, used data from the Mt. Bachelor Observatory and other sites to show how secondary organic aerosols and black carbon change as wildfire smoke ages. This work has important implications for the climate forcing of smoke.

In this analysis, Dan and coauthors show how the PM2.5/CO ratio can be used to track wildfire smoke in urban locations.

In this analysis, Dan and coauthors examined data from 32 Nonattainment areas in the US (cities that fail to meet the US ozone standard) to better understand the relationship between nitrogen oxides (mainly from vehicles) and Ozone. The analysis showed how ozone was reduced in 2020 in the Eastern U.S. (due to COVID-19 related traffic reductions) but increased in the Western U.S. due to the large number and area of wildfires burning that year.
