Title: Waveband Integrated Bioaerosol Sensor (WIBS4) for MARCUS Field Campaign Report

Abstract

The Waveband Integrated Bioaerosol Sensor Mk. 4 (WIBS4) of Karlsruhe Institute of Technology (KIT) was operated as part of the Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS) field campaign from November 2017 to March 2018. WIBS4 was integrated in the U.S. Department of Energy Atmospheric Radiation Measurement (ARM) user facility second ARM Mobile Facility (AMF2), which was installed on the RSV Aurora Australis Australian Antarctic supply vessel during MARCUS. The aim of this campaign was to characterize the Southern Ocean boundary layer coarse-mode aerosol in terms of the fraction of biological or biogenic compounds. This work was done in close collaboration with Greg McFarquhar from the University of Oklahoma, the principal investigator (PI) for MARCUS, as well as Paul DeMott from Colorado State University, who concurrently sampled particle filters for off-line analysis of the ice nucleating particle concentrations. During four voyages of the vessel between Hobart, Tasmania and the Australian Antarctic stations Davies, Casey, and Mawson, as well as Macquarie Island, fluorescent biological aerosol particles (FBAP) were monitored by the WIBS4 in the size range from 0.5 to 10 μm. A FBAP is defined by its fluorescent behavior that gives simultaneous signals in the F1 (λexcitation=280nm,more » λemission=310- 400nm) and F3 (λexcitation=370nm, λemission=420-650nm) channels of the WIBS4 (Toprak and Schnaiter, 2013).« less
