Abstract. A new sea ice configuration, GSI8.1, is implemented in the Met Office global coupled configuration HadGEM3-GC3.1 which will be used for all CMIP6 simulations. The inclusion of multi-layer thermodynamics has required a of a semi-implicit coupling scheme between atmosphere and sea ice to ensure stability of the solver. Here we describe the sea ice model component and show that the Arctic thickness and extent compare well with observationally based data.
