The UC-Irvine research group proposes to collect whole air samples aboard the NASA DC-8 aircraft during the 2012 campaign of the Southeast Asia Composition, Cloud, Climate Coupling Regional Study (SEAC4RS) field mission. More than 70 trace gases will be identified and quantified at our Irvine laboratory, including C2-C10 NMHCs, C1-C2 halocarbons, C1-C5 alkyl nitrates, and selected sulfur compounds. This will be achieved using our established technique of airborne whole air sampling followed by laboratory analysis using gas chromatography (GC) with flame ionization detection (FID), electron capture detection (ECD), and mass spectrometric detection (MSD). Our experimental procedures will build on those that have been successfully employed for numerous prior NASA field missions, for example PEMTropics B, TRACE-P, INTEX-A and B, and ARCTAS.
