This dataset contains HClO3 and HClO4 (30min-averaged) data, measured with a nitrate-chemical ionization atmospheric pressure interface time-of-flight mass spectrometry (CI-APi-TOF), during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition from 15 January 2020 to 30 June 2020. These measurements were performed in the Swiss container on board of Research Vessel Polarstern during the MOSAiC campaign. The data columns include the Time in Coordinated Universal Time (UTC), the latitude and longitude of Research Vessel Polarstern, the MOSAiC event label, and the unit of the data has been indicated in each data column.
