Seasonal mean vertical distributions of ozone obtained with Mast‐Brewer electrochemical ozone sondes are presented for Aspendale (38°S, 145°E) from winter 1965 through winter 1967. They reveal a winter‐spring maximum at the 30 to 40 mb level and a marked seasonal variation in the 100 to 350 mb region. Transient and standing eddy transport of ozone is found to be important at some levels, while vertical motion plays a significant role. The zonally averaged mean meridional transport could at most be comparable with the transient eddy term in some seasons. Year to year variations between corresponding seasons are found to be large and significant in all seasons. Large variations in the ozone content of different altitude layers occur in opposite senses, and apparently systematic patterns of change with altitude and time are found for Aspendale and also for Boulder, Colorado (40°N, 105°W). These could be related to the quasi‐biennial oscillation of other atmospheric properties. The data are not considered sufficient to establish representative climatological means.
