We know the climate is changing and these changes vary spatially but global climate projections cannot provide the detailed spatial resolution required for impacts and adaptation research.

The Coordinated Regional Downscaling Experiment (CORDEX) addresses this by producing regional scale projections for all continental regions.

Here we evaluate the performance of CORDEX simulations over Australia against gridded observations of temperature and precipitation. The ensemble mean produces a good representation of Australian climate, while the individual ensemble members each have unique errors.

The varying regional model capabilities identified here serve as a foundation for the development of future regional climate projections and impact assessments for Australia
