Abstract
Abstract. According to current estimates, atmospheric new particle formation
(NPF) produces a large fraction of aerosol particles and cloud condensation
nuclei in the Earth's atmosphere, which have implications for health
and climate. Despite recent advances, atmospheric NPF is still
insufficiently understood in the lower troposphere, especially above the
mixed layer (ML). This paper presents new results from co-located airborne
and ground-based measurements in a boreal forest environment, showing that
many NPF events (∼42 %) appear to start in the topmost part
of the residual layer (RL). The freshly formed particles may be entrained into the growing
mixed layer (ML) where they continue to grow in size, similar to the aerosol
particles formed within the ML. The results suggest that in the boreal
forest environment, NPF in the upper RL has an important contribution to the
aerosol load in the boundary layer (BL).
