dc.description.abstractWe present a case study based on balloon-borne ozone measurements during the SouthEast American Consortium for Intensive Ozonesonde Network Study in August–September 2013. Data from Socorro, NM (34°N, 107°W) show a layer of anomalously low ozone in the upper troposphere (UT) during 8–14 August. Back trajectories, UT jet analyses, and data from the Microwave Limb Sounder (MLS) on the Aura satellite indicate that this feature originated from the marine boundary layer in the eastern/central tropical Pacific, where several disturbances and one hurricane (Henriette) formed within an active region of the Intertropical Convergence Zone in early August 2013. The hurricane and nearby convection pumped boundary layer air with low ozone (20–30 ppbv) into the UT. This outflow was advected to North America 3–5 days later by a strong subtropical jet, forming a tongue of low ozone observed in MLS fields and a corresponding layer of low ozone in Socorro vertical profiles.
dc.description.sponsorshipData from SEACIONS can be obtained athttp://croc.gsfc.nasa.gov/seacions. MLSv4.2 data are available from the NASAGoddard Space Flight Center EarthSciences (GES) Data and InformationServices Center. SEACIONS was sup-ported by the NASA UARP (K.W. Jucks)and grants from the NASA TroposphericChemistry Program (J. Al-Saadi and A.Pszenny) to NOAA (B.J.J.), and to thePennsylvania State University (A.M.T.)through grant NNX12AF05G. Specialthanks to Patrick Cullis and ChanceSterling (CIRES at NOAA/GMD), GaryMorris (St. Edwards University), MichaelHerman (New Mexico Tech), and tostudents who collected data at ?veSEACIONS sites. Thanks to GMAO forMERRA and other GEOS analyses, espe-cially Krzysztof Wargan for providingthe OMI/MLS assimilated ?elds. Criticalsupport for the Socorro SEACIONSoperations was provided by the NewMexico Tech Physics Department, theLangmuir Laboratory for AtmosphericResearch, and Edward Gangemi (NewMexico Tech Research Division). Work atthe Jet Propulsion Laboratory, CaliforniaInstitute of Technology was done undercontract with the National Aeronauticsand Space Administration.
