Equivalent black carbon concentration measured during the Arctic Ocean 2018 expedition
Paul Zieger, Linn Karlsson
Equivalent black carbon (eBC) concentration was measured using a multi-angle absorption photometer (MAAP, Thermo Scientific Inc., Model 5012, Germany). Measurements were performed onboard Swedish icebreaker Oden during August and September 2018 along the track of the Arctic Ocean 2018 expedition in the central Arctic Ocean.
Black 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.
The MAAP was installed behind a whole-air inlet located on the 4th deck of I/B Oden, where air was continuously sampled. The MAAP measures light absorption at a wavelength of 637 nm, which is the wavelength at which black carbon is the primary absorber. The time series presents the entire quality-assured data (including periods with the possible influence of ship pollution).

Data description
The data is provided in one comma-separated values (csv) file (1.34 MB).
- Column 1: Time (UTC), month/day/year HH:MM
- Column 2: Equivalent black carbon concentration (in microgram per cubic metre)
Only data with the instrument status flag (000000) are included (periods with zeroing or filter change are not included). Full details on the technical details of the MAAP and its used algorithms can be found in Petzold and Schönlinner (2004).
Comments
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.
The ship track with latitude and longitude information can be found in the Navigation, meteorological and surface seawater data from the Arctic Ocean 2018 expedition data set.
