[{"title":"Sulfuric acid condensation sink calculated for the Arctic Ocean 2018 expedition","summary":"The condensation sink is a measure of the sulfuric acid lifetime against condensation on preexisting aerosol particles. Dimensionally it is the inverse of a time (reported in per second) and it is calculated starting from the aerosol size distribution.\r\n\r\nA large condensation sink means that sulfuric acid and other gaseous species with a similarly low volatility (e.g., iodic and methanesufonic acid) will rapidly condense and their atmospheric concentration will decrease.\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.
