Summertime boreal forest atmospheric chemistry and physics (HUMPPA-COPEC 2010)
Editor(s): A. Goldstein, D. Heard, and M. Kanakidou
The HUMPPA-COPEC 2010 intensive field measurement campaign was conducted at the Boreal forest research station SMEAR II (Station for Measuring Ecosystem-Atmosphere Relation) in Hyytiälä, Finland from 12 July–12 August 2010. This campaign was focused on characterizing the summertime chemistry and physics over the Boreal forest when emission fluxes of volatile organic compounds (VOC), OH initiated photochemistry, and particle growth rates reach their seasonal maximum. An international consortium co-ordinated by the Max Planck Institute for Chemistry, Germany and the University of Helsinki, Finland was assembled to quantity a comprehensive suite of gas and particle phase species. The natural biogenic emissions from the surrounding coniferous forest were characterized under the long summer daylight and warm temperature conditions. Furthermore the campaign sought to capture and characterize influences from biomass burning, urban anthropogenic pollution and nearby sawmills at the site.
