Unlike greenhouse gases, which are well mixed in the atmosphere, ozone exhibits marked regional patterns, particularly at high southern latitudes. Adequate account of these patterns has tangible benefits for the accuracy of climate simulation over seasonal to decadal time scales. The sensitivity of regional surface climate to the representation of ozone in climate models, and how this sensitivity depends on greenhouse gas changes, are focal points for research Dr Klekociuk leads under the Australian Antarctic Program.
In conducting his research, Dr Klekociuk collaborates on the development and analysis of climate model simulations, particularly through the Chemistry-Climate Model Initiative (CCMI). He also leads an Australian-Chinese collaboration that is investigating long-term ozone variability in East Antarctica.
Dr Klekociuk contributes to the Antarctic Climate and Ecosystems Cooperative Research Centre as leader of the Future Climate and Sea Level group within the Australian Antarctic Division’s ‘Antarctica and the Global System’ program.
