Two consecutive cruises in the Weddell Sea, Antarctica, in winter/spring 2013 provided the first direct observations of sea salt aerosol (SSA) production from blowing snow above sea ice, thereby validating a model hypothesis to account for winter time SSA maxima in polar regions not explained otherwise. Concentration, size distribution and chemical composition of airborne snow particles, sea salt aerosol and snow on sea ice where measured on board RV Polarstern as well as on the sea ice during ice stations. Funding was provided by NERC projects NE/J023051/1 and NE/J020303/1. : Two consecutive Antarctic expeditions were carried out in the Weddell Sea aboard the German icebreaker RV Polarstern in 2013, the Antarctic Winter Ecosystem ClimateStudy(AWECS), ANT-XXIX/6 between 8 June and 12 August, and the spring expedition ANT-XXIX/7 between 14 August and 16 October. Methods are described in detail in Frey et al., 2019. : Detection limits and data quality are described in detail in Frey et al., 2019.
