[{"name":"oden-ao-2018-aerosol-coarse-1","title":"Coarse-mode particle number size distribution data collected during the Arctic Ocean 2018 expedition","summary":"Aerosol particle number size distributions in the size range 0.15\u2060\u200a\u2013\u200a\u206010 micrometre were measured with a white-light aerosol spectrometer (WELAS) with a Promo 2000H system (Palas GmbH, 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.\r\n\r\nAtmospheric aerosol particles affect climate by scattering and absorbing solar radiation and by modifying cloud properties. The particle size distribution is an important parameter that determines for example the atmospheric residence time, the optical properties, and the interaction with atmospheric water (cloud activation).\r\n\r\nThe WELAS was installed behind a whole-air inlet located on the 4th deck of I\/B Oden, where air was continuously sampled.","citations":"Siegel K, Karlsson L, Zieger P, Baccarini A, Schmale J, Lawler M, Salter M, Leck C, Ekman AML, Riipinen I, Mohr C (2021) Insights into the molecular composition of semi-volatile aerosols in the summertime central Arctic Ocean using FIGAERO-CIMS.
