Abstract

Biogenic hydrocarbons (BVOC) are highly reactive against hydroxyl and nitrate radicals and ozone. They thus play an important role in controlling the oxidation capacity of the atmosphere. Recently, in order to explain observations of high OH radicals in areas affected by BVOC emissions significant progress has been made in our understanding of isoprene oxidation chemistry. In this study, using the 3-dimensional chemistry and transport model TM5-MP, coupled with Rosenbrock solver as derived by the KPP software and the detailed updated MOGUNTIA chemical scheme we evaluated the impact of isoprene and terpenes on the oxidation capacity on the global troposphere. Simulations were performed for the year 2006 taking into consideration and neglecting isoprene and terpenes chemistry. The differences between these simulations resulting from the BVOC chemistry were investigated, focusing on the concentrations of CO, O₃ and OH radical. The performance of the model was evaluated by comparing the results with field observations from the WOUDC and NOAA.
