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 2: Observed water mass changes with comparison to models

Jan is leading a paper looking at observed water mass changes. As part of this paper (or a Part 2 paper) we'll look at how the models (i.e. historical experiment and perhaps HighResMIP) compare. This work will define a bunch of useful metrics that we can use in future papers.

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

I'm leading this paper.

Paper 5: Water masses in the CMIP models

Could consider fidelity compared to observations, single forcing, variability

Paper 6: Energy and water cycle anomaly pathways

This will involve running ACCESS-OM2.
