Kennaook / Cape Grim Baseline Air Pollution Station: Measuring atmospheric composition since 1976.

It is 1 of 3 international reference stations. (Cape Grim, Hawaii and Canada are shown on a globe.)

They all measure air that hasn't been in recent contact with land – called Baseline air.

At Kennaook, the prevailing winds bring clean air from the vast Southern Ocean. This air becomes part of the world's longest, complete archive of pristine samples.

The station measures:
• ozone-depleting chemicals
• greenhouse gases
• aerosols
• persistent organic pollutants
• and much more.

Its long-term records inform the world about the drivers of climate change, such as carbon dioxide (CO2) and aerosols.

Kennaook measurements are freely available and have been utilised in hundreds of research papers worldwide.

The station's data are cited in all United Nations international assessments of climate change and ozone depletion.
