The Southern Hemisphere mid-latitudes, particularly the area around south-eastern Australia and New Zealand, has been suggested as one of the regions where ozone recovery might first be detected…
The 2013 ozone hole was relatively small, with about 15-17 ozone holes out of the last 20 (1994-2013) having been bigger/deeper (depending on the metric used), and only 2-4 having been smaller (2002, 2004, 2010, 2012).

Tropospheric ozone is a greenhouse gas, ranked third in anthropogenic radiative forcing after CO2 and CH4. Ozone in the troposphere makes up an important fraction of the atmospheric shield against ultraviolet … radiation particularly when stratospheric ozone depletion events occur.
The 2012 ozone hole was one of the smallest since the late 1980fs due to a warmer than normal mid]lower … stratosphere over the Antarctic region this year. The development and recovery of the 2012 ozone hole will … be shown via a set of metrics based on the Ozone Monitoring Instrument (OMI)…

The Southern Hemisphere (SH) is relatively data sparse in terms of ozone monitoring, particularly in the mid-latitudes where there are few long term records. The Australian Bureau of Meteorology possesses continuous datasets from the Australian region dating back to the 1950s (Dobson) or 1960s…
Ozone in the troposphere has four important roles. Tropospheric ozone is a greenhouse gas…

Results of ongoing investigations into patterns of interannual variability in total column ozone as measured by the Bureau of Meteorology’s Dobson network over the Australian region are presented. At all latitudes, total column ozone increases during winter and spring…
