ASCOS-aerosol number size distributions (FMI)

ASCOS was an interdisciplinary expedition to the central Arctic on the icebreaker Oden from 1 August to 9 September 2008. The expedition focused on processes relating to cloud formation in the summer Arctic and included observations of marine biology and chemistry, atmospheric chemistry, physical oceanography, aerosol chemistry and physics, and meteorology. The data in this data set includes aerosol particle number size distributions measured with a DMPS (size range: 7-500 nm) and an APS (size range: 0.5 - 10 um).
