My research is focused on how changes in stratospheric ozone can influence the rest of the Earth system. To do this, I have analysed previously completed model simulations (that were conducted in support of the last IPCC report), and used a global climate model to complete my own simulations. As global climate models evolve to further complexity to become Earth System Models, it allows us to address research questions in a consistent framework and my work will be breaking new ground in linking the stratosphere to other parts of the Earth system.

My work has three specific objectives:

- Examine stratospheric ozone changes and associated climate impacts in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP).

- Study the links between decadal to inter-decadal internal climate variability in sea surface temperatures and stratospheric ozone.

- Investigate the climate forcing from stratospheric ozone recovery in the future.

This research involves two parts: 1) analysis of existing ACCMIP simulations and 2) climate model simulations to look at the impact of recovery scenarios and internal climate variability for stratospheric ozone. The Community Earth System Model (CESM) will be used for these latter experiments. This is a coupled climate model, which allows conducting fundamental research into the Earth’s past, present, and future climate system.
