Raw data were collected at 1 Hz frequency and then averaged for 60 s in order to improve the signal to noise ratio. The datetime is reported as UTC in the format yyyy-mm-dd HH:MM:SS.
Concentration is reported as a mixing ratio in parts per bilion. The instrument was calibrated after the campaign and the data were corrected for a baseline drift that affected the instrument.
We used an Hampel type filter to remove outliers and spikes related with short-term instrument malfunction (e.g., flow variations).
The last column in the dataset is a flag to separate between clean data and data that are potentially influenced by the ship exhaust: 1 indicates clean data and 2 contaminated data.
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.

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).
