    • Glyoxal yield from isoprene oxidation and relation to formaldehyde: chemical mechanism, constraints from SENEX aircraft observations, and interpretation of OMI satellite data 

      Miller, Christopher Chan; Jacob, Daniel J.; Marais, Eloise A.; Yu, Karen; Travis, Katherine R.; Kim, Patrick S.; Fisher, Jenny A.; Zhu, Lei; Wolfe, Glenn M.; Hanisco, Thomas F.; Keutsch, Frank N.; Kaiser, Jennifer; Min, Kyung-Eun; Brown, Steven S.; Washenfelder, Rebecca A.; Abad, Gonzalo González; Chance, Kelly (Copernicus Publications, 2017-07-18)
      Glyoxal (CHOCHO) is produced in the atmosphere by the oxidation of volatile organic compounds (VOCs). Like formaldehyde (HCHO), another VOC oxidation product, it is measurable from space by solar backscatter. Isoprene ...
    • Impact of evolving isoprene mechanisms on simulated formaldehyde: An inter-comparison supported by in situ observations from SENEX 

      Marvin, Margaret R.; Wolfe, Glenn M.; Salawitch, Ross J.; Canty, Timothy P.; Roberts, Sandra J.; Travis, Katherine R.; Aikin, Kenneth C.; Gouw, Joost A. de; Graus, Martin; Hanisco, Thomas F.; Holloway, John S.; Hübler, Gerhard; Kaiser, Jennifer; Keutsch, Frank N.; Peischl, Jeff; Pollack, Ilana B.; Roberts, James M.; Ryerson, Thomas B.; Veres, Patrick R.; Warneke, Carsten (Elsevier, 2017-05-30)
      Isoprene oxidation schemes vary greatly among gas-phase chemical mechanisms, with potentially significant ramifications for air quality modeling and interpretation of satellite observations in biogenic-rich regions. In ...
    • Modeling Ozone in the Eastern U.S. using a Fuel-Based Mobile Source Emissions Inventory 

      McDonald, Brian C.; McKeen, Stuart A.; Cui, Yu Yan; Ahmadov, Ravan; Kim, Si-Wan; Frost, Gregory J.; Pollack, Ilana B.; Peischl, Jeff; Ryerson, Thomas B.; Holloway, John S.; Graus, Martin; Warneke, Carsten; Gilman, Jessica B.; Gouw, Joost A. de; Kaiser, Jennifer; Keutsch, Frank N.; Hanisco, Thomas F.; Wolfe, Glenn M.; Trainer, Michael (ACS Publications, 2018-06-05)
      Recent studies suggest overestimates in current U.S. emission inventories of nitrogen oxides (NOx = NO + NO₂). Here, we expand a previously developed fuel-based inventory of motor-vehicle emissions (FIVE) to the continental ...
    • Observational constraints on glyoxal production from isoprene oxidation and its contribution to organic aerosol over the Southeast United States 

      Li, Jingyi; Mao, Jingqiu; Min, Kyung‐Eun; Washenfelder, Rebecca A.; Brown, Steven S.; Kaiser, Jennifer; Keutsch, Frank N.; Volkamer, Rainer; Wolfe, Glenn M.; Hanisco, Thomas F.; Pollack, Ilana B.; Ryerson, Thomas B.; Graus, Martin; Gilman, Jessica B.; Lerner, Brian M.; Warneke, Carsten; Gouw, Joost A. de; Middlebrook, Ann M.; Liao, Jin; Welti, André; Henderson, Barron H.; McNeill, V. Faye; Hall, Samuel R.; Ullmann, Kirk; Donner, Leo J.; Paulot, Fabien; Horowitz, Larry W. (AGU Pubication, 2016-07-31)
      We use a 0‐D photochemical box model and a 3‐D global chemistry‐climate model, combined with observations from the NOAA Southeast Nexus (SENEX) aircraft campaign, to understand the sources and sinks of glyoxal over the ...
