SOCRATES: Multi-Network Composite Highest Resolution Radiosonde Data


This data set contains a composite of the highest vertical resolution (i.e. the “native resolution”) upper air sounding data from all sources for the Southern Ocean Clouds, Radiation, Aerosol Transport Experimental Study (SOCRATES) project in the EOL Sounding Composite (ESC) columnar ASCII format. The data set contains 1888 soundings including the dropsonde data (109 soundings) from the NSF/NCAR Gulfstream-V HIAPER aircraft and the radiosonde data from the ships R/V Investigator (234 soundings), RSV Aurora Australis (208 soundings) and from 19 Australia, New Zealand, and Antarctica operational locations (1337 soundings).
