[{"title":"Aerosol and droplet size distributions and concentrations measured during the Arctic Ocean 2018 expedition","summary":"Aerosol and droplet size distributions and concentrations were measured by a Forward Scattering Spectrometer Probe (model FSSP-100). The FSSP was installed on the roof of the 'triple-lab' container on deck 4 of the icebreaker Oden. It was mounted on an actively rotator which kept the FSSP pointed into the wind. The FSSP is aspirated and the sample volume corrected for the impact of ambient wind speed on the sample flow rate.\r\n\r\nThe primary purpose of this data is to measure the droplet size distribution during fog events, but large aerosol particles are also measured during fog free periods.\r\n\r\nFailure of the anti-icing heating resulted in ice build-up intermittently blocking the laser path, resulting in gaps in the time series. The laser failed before the end of the project. Data is available from August 1 2018 through September 6 2018. This covers transit of the Oden into the ice and most of the ice-drift period near the North Pole.","citations":"","comments":"Instrumentation operated by Ian Brooks and Peggy Achtert (School of Earth and Environment, University of Leeds, UK).
