[Gros2011] Gros, V., C. Gaimoz, F. Herrmann, T. Custer, J. Williams, B. Bonsang, S. Sauvage, N. Locoge, O. d'Argouges, R. Sarda-Esteve, et al., "Volatile organic compounds sources in Paris in spring 2007. Part I: qualitative analysis", Environmental Chemistry, vol. 8, no. 1: CSIRO, pp. 74–90, 2011.
High-time-resolution measurements of volatile organic compounds (VOCs) were performed in the Paris city centre in spring 2007. The studied region was influenced mainly by air masses of two origins: (1) from the Atlantic Ocean, and (2) from north-eastern Europe. Although the baseline levels (i.e. those not influenced by local emissions) of non-methane hydrocarbons (NMHC) and CO were only slightly impacted by changes in the air-mass origin, oxygenated compounds such as acetone and methanol showed much higher baseline levels in continentally influenced air masses. This suggests that NMHC and CO mixing ratios were mainly influenced by local-to-regional-scale sources whereas oxygenated compounds had a more significant continental-scale contribution. This highlights the importance of measuring VOCs instead of NMHC alone in source classification studies. The period of Atlantic air influence was used to characterise local pollution, which was dominated by traffic-related emissions, although traffic represents the source of only one third of total VOCs emissions in the local inventory. In addition to traffic-related sources, additional sources were identified; in particular, emissions from dry-cleaning activities were identified by the use of a specific tracer (i.e. tetrachloroethylene).
[Colomb2009] Colomb, A., V. Gros, S. Alvain, R. Sarda-Esteve, B. Bonsang, C. Moulin, T. Klüpfel, and J. Williams, "Variation of atmospheric volatile organic compounds over the Southern Indian Ocean (30–49 S)", Environmental Chemistry, vol. 6, no. 1: CSIRO, pp. 70–82, 2009.
Considering its size and potential importance, the ocean is poorly characterised in terms of volatile organic compounds (VOC) that play important roles in global atmospheric chemistry. In order to better understand their potential sources and sinks over the Southern Indian Austral Ocean, shipborne measurements of selected species were made during the MANCHOT campaign during December 2004, on board the research vessel Marion Dufresne. Along the transect La Réunion to Kerguelen Island, air measurements of selected VOC (including dimethylsulfide (DMS) isoprene, carbonyls and organohalogens), carbon monoxide and ozone were performed, crossing subtropical, temperate and sub-Antarctic waters as well as pronounced subtropical and sub-Antarctic oceanic fronts. The remote marine boundary layer was characterised at latitudes 45–50°S. Oceanic fronts were associated with enhanced chlorophyll and biological activity in the seawater and elevated DMS and organohalogens in the atmosphere. These were compared with a satellite-derived phytoplankton distribution (PHYSAT). Diurnal variation for isoprene, terpenes, acetone and acetaldehyde was observed, analogously to recent results observed in mesocosm experiments.
