Important amounts of reactive gases and particles are emitted over equatorial Africa by human activities and naturally by forests, lightning and soils. The different transport processes that characterize this region during the monsoon season (e.g. African and Tropical Easterly Jets, deep convection) can redistribute these emissions downwind out of Africa and, hence, have an impact on the regional as well as on the global ozone (O3) budget. The main objective of my thesis is to improve our knowledge of the impact of these emissions and transport processes on the chemical composition of the atmosphere over equatorial Africa. For this purpose, the in-situ data measured during the AMMA field campaign which took place over west Africa in summer ...
