Description:
In the latest IPCC report the exchange of biogenic volatile organic compounds (BVOCs) were identified as representing some of the greatest unknowns with respect to their impact on the climate system. The impact of the BVOCs may be on the order of magnitude of the combined effect of CO2, CH4 and N2O taken together. The release of BVOCs to the atmosphere from natural ecosystems may be in the order of ten times larger than the anthropogenic emissions of VOCs. It is therefore of the greatest importance to study the combined effects of CO2, CH4 and BVOC exchanges between natural ecosystems and the atmosphere. This project will take advantage of existing infrastructure supporting CO2 and CH4 flux measurements and add measurements of BVOCs to complete the picture of how natural ecosystem land atmosphere exchanges are affecting climate. In complimentary support of this project will be a Marie Curie Excellence Grant awarded to study the exchanges of BVOCs in northern Sweden. This continuation project on an already FORMAS funded project (under the climate program) will enable an addition to this project to ensure a comprehensive coverage of measurements representing a range of different sites in Sweden.
