Measurements were performed onboard of the Swedish icebreaker (I\/B) Oden from August to September 2018 as part of the expedition Arctic Ocean 2018. \r\n\r\nBlack carbon is an anthropogenic aerosol resulting from incomplete combustion (e.g. traffic or ship exhaust or industrial emissions). It is relevant for various atmospheric processes such as its influence on radiative transfer within the Earth's atmosphere.\r\n\r\nThe instrument was located on the 4th deck of I\/B Oden, switching hourly between a total and interstitial air inlet, with cutoff sizes of 40 and 1 \u00b5m respectively. 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 m\u00b2 g\u207b\u00b9.","url":"http:\/\/bolin.su.se\/data\/oden-ao-2018-aerosol-ebc-ae33-1","keywords":["Atmosphere","Aerosols","Arctic","Black carbon","AO18","MOCCHA","Icebreaker Oden","Central arctic ocean","Aethalometer","Earth science > Atmosphere > Aerosols"],"creator":{"@type":"Person","name":"Benjamin Heutte, Andrea Baccarini, Paul Zieger, Julia Schmale"},"citation":"Karlsson, L., Baccarini, A., Duplessis, P., Baumgardner, D., Brooks, I.
