Etude de la canicule européenne de 2003 avec les données aéroportées MOZAIC : pollution et transport.

Abstract : This thesis aims to characterise and analyse pollution sources during summer european heat wave 2003 thanks to MOZAIC airborne data. Study of such intense event is necessary because of its probable frequency increase in a climate changing context. MOZAIC dataset contribution with frequent vertical profiles at Frankfurt, Vienna and Paris allows to describe and quantify vertical extension of pollutant anomalies (ozone, carbon monoxide CO, nitrogen oxides) with regards to an 11-years establish climatology. Synoptic condition study of heat wave formation identifies favorable factor to pollution and establishes the prominence of the planetary boundary layer intense expansion. In a second part, lagrangian analysis is used in order to assess impact of primary emissions sources of CO at MOZAIC measurements : European and North American anthropic emissions, and Portuguese biomass fire emissions. In a third part, global chemistry-transport model GEOS-Chem allows to examine important process during the episode (dry deposition and biogenic emissions). Simulations are previously evaluate versus MOZAIC data and sensibility tests utilizing shows the importance of surface-vegetation-atmopshere process and the importance of Portugal fire plumes transport thanks to a daily emission calendar
