Model output containing ocean, atmospheric and sea ice variables from the zstar_triads simulation of the HadGEM3-GC5-LM coupled climate model (1976-2035).

This dataset contains monthly means of ocean, atmospheric and sea ice variables from a 60-year (1976-2035) integration of the HadGEM3-GC5-LM coupled model, with fixed year 2000 control atmospheric composition. The archived model output includes monthly means from the NEMO v4.0.4 ocean component on T, U, V and W grids; monthly means from the SI3 sea ice model; and monthly means from the GAL9 atmosphere-land model. In addition, five-day means of the temperature and salinity ("T grid") and of the meridional velocity ("V grid") over a ten-year period are provided: these were used to estimate the total diapycnal mixing. In this simulation the default lateral tracer diffusion scheme of Redi and Cox is replaced with the Griffies triads scheme (Griffies et al., 1998); it is referred to a “zstar_triads”. The outputs were generated under the Marine LTSS: Climate Linked Atlantic Sector Science (CLASS) project funded by the Natural Environment Research Council (NERC) under reference NE/R015953/1.
