Gregory; Tanner, David J.; Takeuchi, Masayuki; Qu, Hang; Liu, Xiaoxi; Ng, Nga Lee; Crawford, James H.; Fried, Alan; Richter, Dirk; Simpson, Isobel J.; Blake, Donald R.; Blake, Nicola J.; Meinardi, Simone; Kim, Saewung; Diskin, Glenn S.; Digangi, Joshua P.; Choi, Yonghoon; Pusede, Sally E.; Wennberg, Paul O.; Kim, Michelle J.; Crounse, John D.; Teng, Alex P.; Cohen, Ronald C.; Romer, Paul S.; Brune, William; Wisthaler, Armin; Mikoviny, Tomas; Jimenez, Jose L.; Campuzano-Jost, Pedro; Nault, Benjamin A.; Weinheimer, Andrew; Hall, Samuel R.; Ullmann, Kirk (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Emissions and secondary photochemical products from the Daesan petrochemical complex (DPCC), on the west coast of South Korea, were measured from the NASA DC-8 research aircraft during the Korea-United States Air Quality ...
  • Higher measured than modeled ozone production at increased NOx levels in the Colorado Front Range 
    Baier, Bianca C; Brune, William H; Miller, David O; Blake, Donald; Long, Russell; Wisthaler, Armin; Cantrell, Christopher; Fried, Alan; Heikes, Brian; Brown, Steven; McDuffie, Erin; Flocke, Frank; Apel, Eric; Kaser, Lisa; Weinheimer, Andrew (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Chemical models must correctly calculate the ozone formation rate, P(O3), to accurately predict ozone levels and to test mitigation strategies. However, air quality models can have large uncertainties in P(O3) calculations, ...
  • New insights into the column CH2O/NO2 ratio as an indicator of near-surface ozone sensitivity 
    Schroeder, Jason R.; Crawford, James H.; Fried, Alan; Walega, James; Weinheimer, Andrew; Wisthaler, Armin; Muller, Markus; Mikoviny, Tomas; Chen, Gao; Shook, Michael; Blake, Donald R; Tonnesen, Gail S (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Satellite-based measurements of the column CH2O/NO2 ratio have previously been used to estimate near-surface ozone (O3) sensitivity (i.e., NOx or VOC limited), and the forthcoming launch of air quality-focused geostationary ...
  • Observation-based modeling of ozone chemistry in the Seoul metropolitan area during the Korea-United States Air Quality Study (KORUS-AQ) 
    Schroeder, Jason R.; Crawford, James H.; Ahn, Joon-Young; Chang, Limseok; Fried, Alan; Walega, James; Weinheimer, Andrew; Montzka, Denise D.; Hall, Samuel R.; Ullmann, Kirk; Wisthaler, Armin; Mikoviny, Tomas; Chen, Gao; Blake, Donald R.; Blake, Nicola J.; Hughes, Stacey C.; Meinardi, Simone; Diskin, Glenn; Digangi, Joshua P.; Choi, Yonghoon; Pusede, Sally E.; Huey, Greg L.; Tanner, David J.; Kim, Michelle; Wennberg, Paul O. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The Seoul Metropolitan Area (SMA) has a population of 24 million and frequently experiences unhealthy levels of ozone (O3). In this work, measurements taken during the Korea-United States Air Quality Study (KORUS-AQ, 2016) ...
  • Observations of atmospheric oxidation and ozone production in South Korea 
    Brune, William H.; Miller, David O.; Thames, Alexander B.; Brosius, Alexandra L.; Barletta, Barbara; Blake, Donald R.; Blake, Nicola J.; Chen, Gao; Choi, Yonghoon; Crawford, James H.; Digangi, Joshua P.; Diskin, Glenn; Fried, Alan; Hall, Samuel R.; Hanisco, Thomas F.; Huey, Greg L.; Hughes, Stacey C.; Kim, Michelle; Meinardi, Simone; Montzka, Denise D.; Pusede, Sally E.; Schroeder, Jason R.; Teng, Alex; Tanner, David J.; Ullmann, Kirk; Walega, James; Weinheimer, Andrew; Wisthaler, Armin; Wennberg, Paul O. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    South Korea routinely experiences poor air quality with ozone and small particles exceeding air quality standards. To build a better understanding of this problem, in 2016, the KORea-United States cooperative Air Quality ...
