    • 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 ...
    • Mapping hydroxyl variability throughout the global remote troposphere via synthesis of airborne and satellite formaldehyde observations 

      Wolfe, Glenn M.; Nicely, Julie M.; St. Clair, Jason M.; Hanisco, Thomas F.; Liao, Jin; Oman, Luke D.; Brune, William B.; Miller, David; Thames, Alexander; Abad, Gonzalo González; Ryerson, Thomas B.; Thompson, Chelsea R.; Peischl, Jeff; McKain, Kathryn; Sweeney, Colm; Wennberg, Paul O.; Kim, Michelle; Crounse, John D.; Hall, Samuel R.; Ullmann, Kirk; Diskin, Glenn; Bui, Paul; Chang, Cecilia; Dean-Day, Jonathan (PNAS, 2019-05-20)
      The hydroxyl radical (OH) fuels tropospheric ozone production and governs the lifetime of methane and many other gases. Existing methods to quantify global OH are limited to annual and global-to-hemispheric averages. Finer ...
    • Observing atmospheric formaldehyde (HCHO) from space: validation and intercomparison of six retrievals from four satellites (OMI, GOME2A, GOME2B, OMPS) with SEAC4RS aircraft observations over the southeast US 

      Zhu, Lei; Jacob, Daniel J.; Kim, Patrick S.; Fisher, Jenny A.; Yu, Karen; Travis, Katherine R.; Mickley, Loretta J.; Yantosca, Robert M.; Sulprizio, Melissa P.; Smedt, Isabelle De; Abad, Gonzalo González; Chance, Kelly; Li, Can; Ferrare, Richard; Fried, Alan; Hair, Johnathan W.; Hanisco, Thomas F.; Richter, Dirk; Scarino, Amy Jo; Walega, James; Weibring, Petter; Wolfe, Glenn M. (EGU Publications, 2016-11-01)
      Formaldehyde (HCHO) column data from satellites are widely used as a proxy for emissions of volatile organic compounds (VOCs), but validation of the data has been extremely limited. Here we use highly accurate HCHO aircraft ...
    • Towards a satellite formaldehyde – in situ hybrid estimate for organic aerosol abundance 

      Liao, Jin; Hanisco, Thomas F.; Wolfe, Glenn M.; St. Clair, Jason; Jimenez, Jose L.; Campuzano-Jost, Pedro; Nault, Benjamin A.; Fried, Alan; Marais, Eloise A.; Abad, Gonzalo González; Chance, Kelly; Jethva, Hiren T.; Ryerson, Thomas B.; Warneke, Carsten; Wisthaler, Armin (Copernicus Publications, 2019-03-04)
      Organic aerosol (OA) is one of the main components of the global particulate burden and intimately links natural and anthropogenic emissions with air quality and climate. It is challenging to accurately represent OA in ...
