We examine recently collected cloud observations made from the surface of the
Southern Ocean using W-band cloud radar, ceilometer and a polarization capable lidar. The data were collected as part of several ship- and Macquarie Island-based campaigns between 2016 and 2018. By merging the data obtained with the radar and lidar, we determine the cloud boundaries and examine cloud phase and precipitation. We will demonstrate the retrieval of vertical profiles of aerosols in the remote, pristine marine boundary layer made by lidar and illustrate their relationship with low-level clouds. We will present preliminary results of the latitudinal differences in cloud structure across the Southern Ocean.
