The Southern Ocean (SO) provides a unique natural laboratory for studying cloud formation and cloud-aerosol interactions with minimal anthropogenic influence. The Southern Ocean Clouds, Radiation, Aerosol Transport Experimental Study (SOCRATES), was an aircraft-based campaign conducted from Jan 15 to Feb 28, 2018, off the coast of Hobart, Tasmania, utilizing the NSF/NCAR GV research aircraft. The aircraft was equipped with in-situ probes and remote sensors to observe precipitation, cloud particles, and aerosols, providing detailed vertical profiles to characterize the marine boundary layer (MBL) and free troposphere.
