TIPMIP ocean simulations

TIPMIP, the Tipping Point Modelling Intercomparison Project, is an international effort that uses Earth system models to study tipping points in the climate system, such as a collapse of the Atlantic Meridional Overturning Circulation (AMOC).

As part of the NCAS contribution, I am running TIPMIP ocean experiments with the UK Earth System Model, UKESM1.1, for prospective CMIP6+/CMIP7 applications. Each run has a public log describing its set-up and progress.
