- Title
Long-term changes in ozone mini-hole event frequency over the Northern Hemisphere derived from ground-based measurements.

- Abstract
Examines decadal changes of ozone mini-hole event appearance over the Northern Hemisphere midlatitudes, based on daily total ozone data from seven stations having long records (four decades or more) of ozone observations. Various threshold methods for accepting and rejecting the ozone minima as mini-holes; Conclusion that mini-hole event activity is seen to be rather stable when averaged over a decadal time scale if the mini-holes are selected as large negative departures (exceeding 20%) relative to the moving long-term total ozone reference.
