    • BrO and inferred Bry profiles over the western Pacific: relevance of inorganic bromine sources and a Bry minimum in the aged tropical tropopause layer 

      Koenig, Theodore K.; Volkamer, Rainer; Baidar, Sunil; Dix, Barbara; Wang, Siyuan; Anderson, Daniel C.; Salawitch, Ross J.; Wales, Pamela A.; Cuevas, Carlos A.; Fernandez, Rafael P.; Saiz‐Lopez, Alfonso; Evans, Matthew J.; Sherwen, Tomás; Jacob, Daniel J.; Schmidt, Johan; Kinnison, Douglas; Lamarque, Jean-François; Apel, Eric C.; Bresch, James C.; Campos, Teresa; Flocke, Frank M.; Hall, Samuel R.; Honomichl, Shawn B.; Hornbrook, Rebecca; Jensen, Jørgen B.; Lueb, Richard; Montzka, Denise D.; Pan, Laura L.; Reeves, J. Michael; Schauffler, Sue M.; Ullmann, Kirk; Weinheimer, Andrew J.; Atlas, Elliot L.; Donets, Valeria; Navarro, Maria A.; Riemer, Daniel; Blake, Nicola J.; Chen, Dexian; Huey, L. Gregory; Tanner, David J.; Hanisco, Thomas F.; Wolfe, Glenn M. (Copernicus Publications, 2017-12-22)
      We report measurements of bromine monoxide (BrO) and use an observationally constrained chemical box model to infer total gas-phase inorganic bromine (Bry) over the tropical western Pacific Ocean (tWPO) during the CONTRAST ...
    • Formaldehyde in the Tropical Western Pacific: Chemical Sources and Sinks, Convective Transport, and Representation in CAM‐Chem and the CCMI Models 

      Anderson, Daniel C.; Nicely, Julie M.; Wolfe, Glenn M.; Hanisco, Thomas F.; Salawitch, Ross J.; Canty, Timothy P.; Dickerson, Russell R.; Apel, Eric C.; Baidar, Sunil; Bannan, Thomas J.; Blake, Nicola J.; Chen, Dexian; Dix, Barbara; Fernandez, Rafael P.; Hall, Samuel R.; Hornbrook, Rebecca S.; Huey, L. Gregory; Josse, Beatrice; Jöckel, Patrick; Kinnison, Douglas E.; Koenig, Theodore K.; Breton, Michael Le; Marécal, Virginie; Morgenstern, Olaf; Oman, Luke D.; Pan, Laura L.; Percival, Carl; Plummer, David; Revell, Laura E.; Rozanov, Eugene; Saiz‐Lopez, Alfonso; Stenke, Andrea; Sudo, Kengo; Tilmes, Simone; Ullmann, Kirk; Volkamer, Rainer; Weinheimer, Andrew J.; Zeng, Guang (AGU Pubication, 2017-10-06)
      Formaldehyde (HCHO) directly affects the atmospheric oxidative capacity through its effects on HOx. In remote marine environments, such as the tropical western Pacific (TWP), it is particularly important to understand the ...
    • Global airborne sampling reveals a previously unobserved dimethyl sulfide oxidation mechanism in the marine atmosphere 

      Veres, Patrick R.; Neuman, J. Andrew; Bertman, Timothy H.; Assaf, Emmanuel; Wolfe, Glenn M.; Williamson, Christina J.; Weinzierl, Bernadett; Tilmes, Simone; Thompson, Chelsea R.; Thames, Alexander B.; Schroder, Jason C.; Saiz‐Lopez, Alfonso; Rollins, Andrew W.; Roberts, James M.; Price, Derek; Peischl, Jeff; Nault, Benjamin A.; Møller, Kristian H.; Miller, David O.; Meinardi, Simone; Li, Qinyi; Lamarque, Jean-François; Kupc, Agnieszka; Kjaergaard, Henrik G.; Kinnison, Douglas; Jimenez, Jose L.; Jernigan, Christopher M.; Hornbrook, Rebecca S.; Hills, Alan; Dollner, Maximilian; Day, Douglas A.; Cuevas, Carlos A.; Campuzano-Jost, Pedro; Burkholder, James; Bui, T. Paul; Brune, William H.; Brown, Steven S.; Brock, Charles A.; Bourgeois, Ilann; Blake, Donald R.; Apel, Eric C.; Ryerson, Thomas B. (PNAS, 2020-02-18)
      Dimethyl sulfide (DMS), emitted from the oceans, is the most abundant biological source of sulfur to the marine atmosphere. Atmospheric DMS is oxidized to condensable products that form secondary aerosols that affect Earth’s ...
    • An observationally constrained evaluation of the oxidative capacity in the tropical western Pacific troposphere 

      Nicely, Julie M; Anderson, Daniel C.; Canty, Timothy P.; Salawitch, Ross J.; Wolfe, Glenn M.; Apel, Eric C.; Arnold, Steve R.; Atlas, Elliot L.; Blake, Nicola J.; Bresch, James F.; Campos, Teresa L.; Dickerson, Russell R.; Duncan, Bryan; Emmons, Louisa K.; Evans, Matthew J.; Fernandez, Rafael P.; Flemming, Johannes; Hall, Samuel R.; Hanisco, Thomas F.; Honomichl, Shawn B.; Hornbrook, Rebecca S.; Huijnen, Vincent; Kaser, Lisa; Kinnison, Douglas E.; Lamarque, Jean‐Francois; Mao, Jingqiu; Monks, Sarah A.; Montzka, Denise D.; Pan, Laura L.; Riemer, Daniel D.; Saiz‐Lopez, Alfonso; Steenrod, Stephen D.; H. Stell, Meghan; Tilmes, Simone; Turquety, Solene; Ullmann, Kirk; Weinheimer, Andrew J. (AGU Pubication, 2016-06-05)
      Hydroxyl radical (OH) is the main daytime oxidant in the troposphere and determines the atmospheric lifetimes of many compounds. We use aircraft measurements of O₃, H₂O, NO, and other species from the Convective Transport ...
