The results of a limited series of ozone‐sonde ascents made at Christchurch, New Zealand (latitude 43.5°S) during 1965‐66 with Brewer‐Mast electro‐chemical sondes are discussed. It is found that the vertical distribution of ozone and the pattern of its seasonal variation is similar to that found at Aspendale (southeastern Australia, latitude 38.0°S), but that the Christchurch ozone concentrations are greater at all atmospheric levels. It is further shown that at Christchurch the horizontal transport of ozone by transient eddies is southward at all levels and that the annual average vertically integrated flux is not very different from that observed at a comparable latitude in the Northern Hemisphere. Consideration of the middle latitude ozone budget tends to indicate a coefficient of vertical eddy diffusion in the lower stratosphere of the order of 10 5 cm 2 s −1 for the Southern Hemisphere middle latitudes. Major assumptions involved in this estimate are pointed out.
