BIPHOREP research proposal


Our understanding of the role of biogenic emissions, their importance in relation to anthropogenic emissions, and their atmospheric fate in the European boreal regions is very poor due to the lack of studies conducted in this area. However, high biomass densities in boreal forests make them potentially high emission areas of Biogenic Volatile Organic Compounds (hereafter BVOC). Moreover, climate change impacts are estimated to be particularly strong in the boreal regions. These are our impetus to address the issue of BVOC emissions, their quantification, mechanisms and contribution to tropospheric chemistry, which is specifically mentioned in the Environment & Climate Specific Programme (Workprogramme item, task 3). Our work plan will be built upon answering the following key questions: To answer these questions we propose a multinational integrated research project called Biogenic VOC emissions and photochemistry in the boreal regions of Europe (BIPHOREP) whereby we shall carry out a wide range of measurements at different scales in the northern parts of Europe as well as develop and run different models for the interpretation of these data. The emission intensity measurements will be performed at both leaf and canopy level. Ambient air measurements will allow an inverse assessment of the regional biogenic emissions and a comparison of the contribution of biogenic and anthropogenic VOC species to the formation of oxidants. The use and development of models will be crucial at all scales: to derive emission algorithms at leaf level, to relate emissions to the vegetative structure at canopy scale using detailed forest information (i.a. satellite landuse data), and to correlate ozone formation with photochemical and emission modelling at regional scale.

The project products will be:
