“…Forest fires are predicted to become increasingly prevalent and severe with climate change (Abatzoglou and Williams, 2016;Barbero et al, 2015;Jolly et al, 2015). These fires are an important and uncontrolled source of gas-and particle-phase compounds to the atmosphere, including a complex mixture of gas-phase reactive organic carbon, primary organic aerosol (POA), carbon monoxide, carbon dioxide, methane, ammonia, nitrogen oxides, and black carbon (Akagi et al, 2011;Gilman et al, 2015;Hatch et al, 2015Hatch et al, , 2018Koss et al, 2018;Vicente et al, 2013;Yokelson et al, 2013). Many of these emitted compounds are precursors to downwind ozone and secondary organic aerosol (SOA) production (Ahern et al, 2019;Buysse et al, 2019;Gilman et al, 2015;Hennigan et al, 2011;Lim et al, 2019).…”
