Full details on the technical details of the MAAP and its used algorithms can be found in Petzold and Schönlinner (2004). Data were collected during the Arctic Ocean 2018 expedition on board the Swedish icebreaker (I/B) Oden, which was organized by the [Swedish Polar Research Secretariat](https://polarforskningsportalen.se/en/arctic/expeditions/arctic-ocean-2018). 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. 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/oden-ao-2018-navigation-1) data set.
