Abstract
The persistent Southern Ocean (SO) shortwave radiation biases in climate models and reanalyses have been associated with the poor representation of clouds, precipitation, aerosols, the atmospheric boundary layer, and their intrinsic interactions. Capitalizing on shipborne observations collected during the Clouds Aerosols Precipitation Radiation and atmospheric Composition Over the Southern Ocean 2016 and 2018 field campaigns, this research investigates and characterizes cloud and precipitation processes from synoptic to micro scales. Distinct cloud and precipitation regimes are found to correspond to the seven thermodynamic clusters established using a K-means clustering technique, while les..

McFarquhar was supported by the National Science Foundation (NSF) through grants AGS-1628674 and AGS-1762096. The authors acknowledge the thorough work from the CAPRICORN and SOCRATES teams to collect, post-processing, and make available the data sets. The CAPRICORN data was collected using the RV Investigator, we thank the CSIRO Marine National Facility (MNF), the ship's personnel and the scientific team for the efforts made in gathering and post-processing the information. The SOCRATES data were collected using NSF's Lower Atmosphere Observing Facilities. The authors thank the pilots, mechanics, technicians, scientists, software engineers, and project managers of the NCAR EOL Research Aviation Facility for their support in the field and in post-processing data. The authors would like to thank the Australian Bureau of Meteorology Tasmanian regional Office for the forecast support and weather briefings provided during the field campaign with special thanks to Scott Carpentier, Michelle Hollister, Matthew Thomas, and Robert Schaap. We sincerely thank Son Truong for providing the cluster classification from CAPRICORN I and II field campaigns, Yang Wang and Julian Schima for giving access to processed data used in the construction of Figure 9.
