Abstract

Biomass burning (BB) is a large source of reactive compounds in the atmosphere. While the daytime photochemistry of BB emissions has been studied in some detail, there has been little focus on nighttime reactions despite the potential for substantial oxidative and heterogeneous chemistry. Here, we present the first analysis of nighttime aircraft intercepts of agricultural BB plumes using observations from the NOAA WP-3D aircraft during the 2013 Southeast Nexus (SENEX) campaign. We use these observations in conjunction with detailed chemical box modeling to investigate the formation and fate of oxidants (NO ₃ , N ₂ O ₅ , O ₃ , and OH) and BB volatile organic compounds (BBVOCs), using emissions representative of agricultural burns (rice straw) and western wildfires (ponderosa pine). Field observations suggest NO ₃ production was approximately 1 ppbv hr ^-1 , while NO ₃ and N ₂ O ₅ were at or below 3 pptv, indicating rapid NO ₃ /N ₂ O ₅ reactivity. Model analysis shows that >99% of NO ₃ /N ₂ O ₅ loss is due to BBVOC + NO ₃ reactions rather than aerosol uptake of N ₂ O ₅ . Nighttime BBVOC oxidation for rice straw and ponderosa pine fires is dominated by NO ₃ (72, 53%, respectively) but O ₃ oxidation is significant (25, 43%), leading to roughly 55% overnight depletion of the most reactive BBVOCs and NO ₂ .
