[{"name":"oden-ao-2018-aerosol-dmps-1","title":"Aerosol particle number size distribution data collected during the Arctic Ocean 2018 expedition","summary":"Aerosol particle number size distributions in the size range 10\u2060\u200a\u2013\u200a921 nm were measured with a custom built differential mobility particle sizer (DMPS) which uses a mixing condensation particle counter (MCPC; Model 1720 from Brechtel Manufacturing Inc., USA). An additional MCPC 1720 was measuring the total particle number concentration.\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\nMeasurements were performed on the 4th deck of icebreaker Oden during August and September 2018 along the track of the Arctic Ocean 2018 expedition.","citations":"Baccarini A, Karlsson L, Dommen J, Duplessis P, V\u00fcllers J, Brooks IM, Saiz-Lopez A, Salter M, Tjernstr\u00f6m M, Baltensperger U, Zieger P, Schmale J (2020) Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions.
