Ambient air mole fractions of selected volatile organic compounds measured in the University of Colorado container during the 2019-2020 MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition

This dataset contains ambient air mole fractions of selected volatile organic compounds (propane, isobutane, n-butane, and isoprene) measured at a 3-hr time resolution in the Central Arctic during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. The backbone of MOSAiC was the year-round operation of the Research Vessel Polarstern that drifted with the sea ice across the Central Arctic from October 2019 to September 2020. Measurements were performed onboard Polarstern in the University of Colorado sea-container laboratory installed below deck in the forward cargo hold. A ~50 meter (m) long sampling line was deployed from the container to the bow crane to allow measurements forward of the vessel.
