List of Abstracts 167the highest value in the industrial sites. Whereas, other metals i.e. Cr, Ni, Cu and Pb showed the highestvalue the in commercial sites. The toxic metals i.e. As, Hg and Se species are quantified. The correlation ofthe metals with ions i.e. Cl-, NO3-, SO42-, Na+, K+, Mg2+ and Ca2+ are described. The sources of themetals and ions are apportioned by using various models.P-Observations 2.9 ID:4370 10:30Atmospheric composition over Namibia (austral Africa) from the MOZAIC programme.Jean-Pierre Cammas 1 , Bastien Sauvage 1 , Jérémy Vouzelaud 1 , Romain Bort 1 , Jérôme Coquelin 1 , ValérieThouret 1 , Philippe Nédélec 1 , Jean-Marc Cousin 1 , Jérôme Brioude 2 , Herman Smit 3 , Andreas Volz-Thomas 31 CNRS, Université de Toulouse, France2 NOAA, ESRL, Boulder, CO, USA3 Institut fuer Chemie und Dynamik der Geosphaere 2, Forschungszentrum Juelich, GermanyContact: Jean-Pierre.Cammas@aero.obs-mip.frThe general aim is to document the climatology of vertical profiles over Windhoek (Namibia) from 2006-2008 MOZAIC data. This dataset is very dense, i.e. two profiles per day every two day for ozone, carbonmonoxide and meteorological parameters. Windhoek is pretty far away from the African regions whereozone precursors are emitted, either from biomass fires, or from deep continental convection (LiNOx), orfrom anthropogenic sources. It is a place where the impact of long-range transport of these emissions can bedocumented. We will focus on the two seasons during which intra-seasonal variabilities are the largest, i.e.spring (SON) and summer (DJF). During SON, intra-seasonal variabilities come from the long-rangetransport of lower- and upper-tropospheric CO plumes emitted by biomass fires over both southern Africaand southern America. SON is also the season during which stratospheric intrusions may have an impact onthe upper tropospheric ozone distribution down to the latitude of Windhoek (22S). During DJF, intraseasonalvariabilities come from the long-range transport of mid- and upper-tropospheric O3 plumes that weintend to attribute to ozone production processes activated by LiNOx emissions over convective regions bothover southern Africa and southern America.The results show (i) the climatology in SON and DJF, (ii) representative case studies of each class (i.e., lowtroposphericand upper-tropospheric CO plumes, stratospheric intrusions, LiNOx plumes), (iii) the historyand origin of case studies using the Lagrangian dispersion model Flexpart and satellite data for the detectionof biomass fires and lightning flashes, and (iv) MOZAIC composites of every class of plumes anddifferences between the composite and the climatology. General characteristics of the plumes, as well ascomponents of intra-seasonal variabilities coming either from the long-range transport (meteorologicalsituation) or from the emissions are discussed.P-Observations 2.10 ID:4374 10:30Lulin Atmospheric Background Station (LABS, 2,862m MSL): A newly established baseline site inEast AsiaNeng-Huei Lin 1 , Jia-Lin Wang 2 , Chung-Te Lee 3 , Guey-Rong Sheu 11 Department of Atmospheric Sciences, National Central University2 Department of Chemistry, National Central University3 Graduate Institute of Environmental Engineering, National Central UniversityContact: nhlin@cc.ncu.edu.twThe Lulin Atmospheric Background Station (LABS) in Taiwan held its grand opening for operation on 13April 2006.
