BVOCs are key components in the oxidative atmospheric capacity. They play a large role in secondary pollutant formation such as particles or tropospheric ozone. These secondary products have a great impact on air quality and pollution inducing health diseases and troubles in environmental questions (diseases on plants). This research project is involved in the French and Brazilian BIOMASP+ project (task 3: bio-physico-chemical and ambient composition) to provide a clear signature of BVOC emissions over background site (Morro Grande Forest) and the impact of polluted areas (Matão-IAG-USP site) on these emissions. To understand the synergies between these two sites, intensive and extensive observations periods (IOP and EOP) and fields campaigns will be implemented using large panel of on-line and off-line instrumentation. In parallel, plant's laboratory experiments will be performed to characterize the influence of the polluted environment on background site such as forest. To go further, this research work will provide a database to implement the models involved in the task 4 of this project. Main questions during the post-doctoral fellowship are: What are the cocntrations of reactive gases and more particularly BVOC in the two super sites? What is the impact of these cocnentrations on the oxidative atmospheric capacity and secondary compounds formations regarding urban emissions and pollution concentrations? What is the impact of direct plant's BVOC emissions on the global atmospheric chemistry in the forest site? And then, how the BVOC emissions can be influenced by the anthropogenic pollution?
