MARCUS RSV Aurora Australis Radiosonde Data. Version 1.0

The Department of Energy/Atmospheric Radiation Measurement (DOE/ARM) program operated a radiosonde system on-board the RSV Aurora Australis as part of the Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS) field campaign. The Australis conducted servicing cruises to Davis, Casey, and Mawson Stations on the Antarctica coast from its base at Hobart, Tasmania. Radiosondes were released every six hours (00, 06, 12, 18 UTC) during these cruises. This data set includes only those soundings that were released during the SOCARATES (Southern Ocean Clouds, Radiation, Aerosol Transport Experimental Study) field phase (1 January – 28 February 2018). A total of 208 2-second vertical resolution radiosondes are included in this data set.
