File type: CSV (1 file, ~3MB) File structure and contents: - Column 1: Time (midpoint of scan) in UTC, format yyyy-mm-dd HH:MM:SS - Column 2: Total number concentration (measured by MCPC) in particles per cubic centimeter - Column 3 – 30: Number concentration, dN/dlogD per cubic centimeter at bin midpoint diameters (electrical mobility diameter) The size distribution data have been corrected for losses due to diffusion, impaction and sedimentation using the Particle Loss Calculator (von der Weiden et al. 2009) assuming spherical particles with a density of 1 gcm⁻³. Note that periods with the possible influence of ship pollution are included as reliable data and are not removed. The ship track with latitude and longitude information can be found in the [Navigation, meteorological and surface seawater data from the Arctic Ocean 2018 expedition](https://bolin.su.se/data/ao2018-navigation) data set.

The observations were part of the project 'Aerosol-cloud interactions in the High Arctic' (PI Paul Zieger, Department of Environmental Science, Stockholm University; see [MOCCHA project website](https://www.aces.su.se/research/projects/microbiology-ocean-cloud-coupling-in-the-high-arctic-moccha/) with updates).
