Description
Summary:This dataset contains equivalent black carbon (eBC) concentrations, averaged to 10 min time resolution, measured during the year-long MOSAiC expedition from October 2019 to September 2020. The measurements were performed in the Swiss container on the D-deck of Research Vessel Polarstern, using a commercial aethalometer (model AE33, Magee Scientific, Berkeley, USA). The instrument was located behind an automated valve, which switched hourly between a total and an interstitial air inlet, with upper cutoff sizes of 40 and 1 µm respectively. The inlet flow, of 2 liters per minute, was verified biweekly. The dual spot technology of the instrument allowed for a real-time compensation of what is known as the loading effect (Drinovec et al., 2015). Optical absorption was measured at 7 different wavelengths simultaneously, with a 1 second time resolution. We used the absorption at 880 nm (channel 6) to derive eBC, using a mass absorption cross-section value of 7.77 m2g-1.The switching valve caused concentration ... : We thank the Laboratory for Atmospheric Chemistry at the Paul Scherrer Institute for providing the AE33 instrument.We extracted 10 min time resolution positional data from the following datasets: Rex, M (2020, doi:10.1594/PANGAEA.924669), Haas, C (2020, doi:10.1594/PANGAEA.924672), Kanzow, T (2020, doi:10.1594/PANGAEA.924678), Rex, M (2021, doi:10.1594/PANGAEA.926830) and Rex, M (2021, doi:10.1594/PANGAEA.926911). ...
