Objective
To contribute to an improved understanding of some of the most important impacts of the biogenic volatile organic compounds emissions with relevance to major environmental problems at a global and regional scale, e.g. oxidising capacity of the
The emissions of biogenic volatile organic compounds ('BIOVOCs') contribute at a global scale to the
non-methane VOC budget arising from human activity. These emissions are believed to have a large impact on
atmospheric chemistry, even in industrialised areas, but many relevant aspects of this issue are not yet
adequately understood.
The specific tasks of the project are:
-to improve the understanding of how the degradation of BIOVOC does influence the photochemical
ozone formation in the troposphere.
-to quantify the effect of BIOVOCs on the oxidising capacity of the troposphere,
-to provide a better basis for estimating the importance of aerosol formed in the oxidation of BIOVOCs
to the overall aerosol budget.
These tasks will be met through a combination of laboratory and numerical modelling tasks. The laboratory
work will be carried out in the small-scale chambers available in the participating laboratories as well as in the
large EUPHORE photoreactor in Valencia, Spain, that now has become available. The development of
numerical models will be based on reaction schemes developed using the results obtained by the laboratory
studies. These models will be validated by comparison with experimental data obtained under simulated ambient
conditions in the EUPHORE photoreactor.
The investigation will be focused on some of the most important natural hydrocarbons (isoprene, selected
monoterpenes) and on some relevant examples of oxygen-containing species emitted from vegetation.
The expected outcome of the project is an improved understanding of the baseline contribution of BIOVOC to
some important environmental issues and of the interaction between these emissions and anthropogenic ones.
Efforts will be made to develop detailed as well as condensed reaction schemes to be used in numerical models
simulating atmospheric chemistry.
This project is closely related to two other projects: 'SARBVOC', aiming at providing fundamental kinetic
information to be used in the modelling of atmospheric BIOVOC degradation and 'AEROBIC', a field study
on the formation of organic aerosol from natural hydrocarbons.
