A recent publication by Glenn Wolfe, Thomas Hanisco (614), Jason St Clair and coworkers was highlighted as an Editor's Choice article in the 30 October issue of Science Magazine. The study, "Quantifying sources and sinks of reactive gases in the lower atmosphere using airborne flux observations" (Geophys. Res. Lett., 10.1002/2015GL065839 (2015)) uses observations from the 2013 NASA SEAC4RS mission to derive vertical fluxes for a suite of reactive gases, which provide the groundwork for developing a quantitative, comprehensive and self-consistent picture of atmospheric boundary layer processes. According to the highlight, "(this) approach will improve our knowledge of biogenic and anthropogenic emissions, photochemical mechanisms, and deposition."
