A team of researchers use observations from FIREX-AQ to quantify sulfur dioxide emissions from wildfires and agricultural burns across the western US to understand how regional and long-range air quality can be affected, in a new research study supported by AC4.

Using data from the FIREX-AQ field campaign, a new AC4-funded research study develops a comparison between aerosol concentration and the way aerosol particles scatter light in the atmosphere, offering new insights into wildfire smoke evolution.

A new AC4-funded publication utilizes FIREX-AQ observations to evaluate common modeling representations of wildfire smoke plumes and finds they can be improved by expanding the use of observations for heat flux and boundary layer height.
