摘要:The Finnish Centre of Excellence (FCoE) in "Physics, Chemistry, Biology and Meteorology of Atmospheric Composition and Climate Change" (2008–2013) completed its research activity at the end of 2013. The FCoE research was originally focused on enhanced process-level understanding of various couplings between atmospheric CO2 concentrations, photosynthesis, biogenic volatile organic compounds (BVOC), aerosol particles and clouds. During the FCoE period, the scientific scope moved gradually towards the so-called all-scale concept. In this paper we summarize its main scientific achievements, and give an outlook for future scientific activities and focus.
