Summer Total Ozone
Source: Bureau of Meteorology, January 2005
Data is available for measurements of total ozone over Brisbane, Darwin, Melbourne and Macquarie Island. Brisbane and Darwin show a very small rate of ozone depletion over the reporting period, 1956 to 2004 (or 1991 to 2004 in the case of Darwin). Melbourne and Macquarie Island show a significant rate of ozone depletion. However, all show a slight improvement in ozone levels over the past four to five years.
Atmosphere — Stratospheric ozone - General stratospheric ozone
This measures the total amount of ozone in a column of air from the earth’s surface to the top of the atmosphere and thus is a measure if ozone levels are sufficient to protect us from harmful radiation.
Other indicators for this issue:
- A-10 stratospheric chlorine from the major ozone-depleting substances
- A-12 Trend in the area of the ozone hole
- A-13 Surface ultraviolet radiation in Australia
- A-14 Consumption of ozone-depleting substances - Australian consumption of ozone-depleting substances
- A-15 Skin melanoma rates
