The 1996 Antarctic ozone hole
Article Abstract:
A survey of the ozone destruction trends in the Antarctic region suggests the possibility of a deeper South Pole ozone hole in 1996 than it was in 1995. The ozone depletion may increase by as much as 10 Dobson units in the late September-early October average total column ozone value. The ozone destruction is not only influenced by the amount of halogen transported to the polar stratosphere but also by the winter and spring temperatures. Ozone destruction rates are greater for those years that are characterized by the 10hPa easterly winds.

Recovery of Antarctic ozone hole
Article Abstract:
The first signs of ozone layer healing will be observed over Antarctica. Observation of the signs of ozone hole healing are important, since they provide justification for the banning of certain ozone-depleting substances. The ozone-loss rate and the amount of ozone remaining in the 12-20 km altitude on 15 September (S15) are suitable early ozone-healing indicators. Continued monitoring of the two indicators can detect the ozone turnaround about 10 years earlier than by monitoring total ozone alone.

The search for signs of recovery of the ozone layer
Article Abstract:
The high natural variability in ozone abundances, partly due to the solar cycle as well as changes in transport and temperature, could override the relatively small changes expected from the new decrease in ozone-depleting substances. It is therefore unlikely that ozone would stabilize at levels observed before 1980, when a decline in ozone concentrations was first observed.
