BB-FLUX

The 2018 Biomass Burning Fluxes of Trace Gases and Aerosols campaign deployed the CU solar tracker and the CU SOF on the University of Wyoming King Air research aircraft, building on the experience from Pre-BB-FLUX. The campaign was based in the western United States from July to September 2018 and performed 37 research flights aimed at the following objectives:

1. Quantify emission fluxes of CO, CO2, other gases, and particle volume for different fuel types and burn conditions, and test atmospheric models.
2. Characterize plume injection height of plumes that travel decoupled from the ground (top of boundary layer, free troposphere), and evaluate predictions by atmospheric models.
3. Study radical sources and plume chemistry that leads to secondary production of O3, air toxics, and modifies the particle size distribution as plumes age.
4. Explore synergistic benefits of remote sensing and in-situ observations to quantify speciated total emission fluxes from wildfires.

Additionally, measurements of fuel type and loading were made following the campaign by researchers from the National Ecological Observatory Network (NEON).
