My work focuses on the separate influence of GHGs and AAs on water mass change. (Ultimately to better understand regional sea level rise.) A primary data source for this work is the CMIP single forcing experiments.

To tackle this question, we need:

• Metrics for quantifying water mass change in models
• An understanding of the response of the global energy and water cycles to GHG and AA forcing
• An understanding of energy and mass drift / non-conservation in the CMIP models

(I'm supposed to look at variability in water masses too.)

Paper/s 3: Water mass changes in observations and CMIP6 models

Taimoor is leading a paper looking at observed water mass changes. As part of this paper (or as a Part 2 paper) we'll look at how the models compare.

Paper 4: Global water cycle response to GHG and AA forcing

I'm leading this paper.

Paper 5: Energy and water cycle anomaly pathways

This will involve running ACCESS-OM2.
