Sulfuric acid condensation sink calculated for the Arctic Ocean 2018 expedition
Andrea Baccarini, Julia Schmale, Josef Dommen
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.
A 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.
Measurements were performed on the 4th deck of icebreaker Oden during August and September 2018 along the track of the Arctic Ocean 2018 expedition.

Data description
The condensation sink was calculated using the merged particle size distribution measured during the campaign. The calculation is based on the work of Dal Maso et al. 2002. The time resolution is 10 minutes and the condensation sink was calculated only for data that were not affected by the ship exhaust.
The datetime is reported as UTC in the format yyyy-mm-dd HH:MM:SS.
Comments
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.
The merged particle size distribution data used to calculate the condensation sink can be found in the Size distribution of aerosol particles between 2.5 and 920 nm measured during the Arctic Ocean 2018 expedition dataset.
