报告摘要：Increasing evidence has suggested that volatile organic compounds (VOCs), including previously little-characterized VOCs, play an important role in urban ozone photochemistry when affected by biomass burning (BB) smoke. However, the emissions and chemistry of BB VOCs are highly uncertain with many species not currently incorporated in operational air quality models. Here I’ll present our group’s recent and ongoing efforts to measure and model the chemical impacts of reactive organic carbon in the western U.S. wildfire smoke. I will first discuss plume-level knowledge learned from recent WE-CAN and FIREX-AQ aircraft campaigns, that revealed a significant amount of‘missing’organic carbon fluxes and reactivity in current global BB emission inventories and chemical transport models (CTMs). I will then discuss the OH chemistry occurring in the near-field of fire plumes that controls the production of ozone and PAN and affects far-field air quality.
