Ozone concentration measured during the Arctic Ocean 2018 expedition
Andrea Baccarini, Julia Schmale, Josef Dommen
Ozone was measured with a 2B Technology ozone monitor (model 205). The concentration is reported as a mixing ratio in parts per billion [ppb], at 60 seconds average.
Ozone is a trace gas that can be formed directly in the troposphere (the most important formation pathway is the photochemical reaction of volatile organic compounds with NO,,x,,) or entrained from the stratosphere where it is formed directly from the reaction of molecular oxygen with UV light. Ozone is an important oxidant in the atmosphere and participate in several chemical reactions.
Measurements were performed on the 4th deck of icebreaker Oden during August and September 2018 along the track of the Arctic Ocean 2018 expedition.

Data description
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.

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. 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 with updates).
