  • An Inversion Framework for Optimizing Non-Methane VOC Emissions Using Remote Sensing and Airborne Observations in Northeast Asia During the KORUS-AQ Field Campaign 
    Choi, Jinkyul; Henze, Daven K.; Cao, Hansen; Nowlan, Caroline R.; González Abad, Gonzalo; Kwon, Hyeong-Ahn; Lee, Hyung-Min; Oak, Yujin J.; Park, Rokjin J.; Bates, Kelvin H.; Maasakkers, Joannes D.; Wisthaler, Armin; Weinheimer, Andrew J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We aim to reduce uncertainties in CH2O and other volatile organic carbon (VOC) emissions through assimilation of remote sensing data. We first update a three-dimensional (3D) chemical transport model, GEOS-Chem with the ...
  • Evaluation of Secondary Organic Aerosol (SOA) Simulations for Seoul, Korea 
    Oak, Yujin J.; Park, Rokjin J.; Jo, Duseong S.; Hodzic, Alma; Jimenez, Jose L.; Campuzano-Jost, Pedro; Nault, Benjamin A.; Kim, Hwajin; Kim, Hyeonmin; Ha, Eunjo S.; Song, Chang-Keun; Yi, Seung-Muk; Diskin, Glenn S.; Weinheimer, Andrew J.; Blake, Donald R.; Wisthaler, Armin; Shim, Mihee; Shin, Yoonmi (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Organic aerosols (OA) represent a significant fraction of total submicron particulate matter (PM1) concentrations globally, including densely populated megacities such as Seoul. However, scientific understanding of the ...
  • Observed versus simulated OH reactivity during KORUS-AQ campaign: Implications for emission inventory and chemical environment in East Asia 
    Kim, Hyeonmin; Park, Rokjin J.; Kim, Saewung; Brune, William H.; Diskin, Glenn S.; Fried, Alan; Hall, Samuel R.; Weinheimer, Andrew J.; Wennberg, Paul; Wisthaler, Armin; Blake, Donald R.; Ullmann, Kirk (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We present a holistic examination of tropospheric OH reactivity (OHR) in South Korea using comprehensive NASA DC-8 airborne measurements collected during the Korea–United States Air Quality field study and chemical transport ...
