WIBS4 for Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS)

Sea spray aerosol particles originate from the sea surface microlayer which is enriched by biological particles and biogenic compounds. The aerosolization of these compounds might be an important source for ice nucleating particles in the remote Southern Ocean. The Wideband Integrated Bioaerosol Sensor (WIBS) detects bioaerosol particles based on fluorescence measurements in three excitation/emission wavebands on a single particle basis. During the Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS) project, the WIBS4 instrument of Karlsruhe Institute of Technology (KIT) will monitor the Fluorescent Biological Aerosol Particles (FBAP) of the Southern Ocean boundary layer as part of the second ARM Mobile Facility (AMF2) installed on the Aurora Australis.

The WIBS4 FBAP data collected during the MARCUS cruises will complement other AMF2 aerosol and remote sensing measurements as well as the filter-based analyses of the aerosol ice nucleation properties and chemical composition.
