This record collates eight global model simulations of monthly means of ocean, atmospheric and sea ice variables from a 60-year (1976-2035) integration of the Hadley Centre Global Environment Model version 3, using the sea ice component of the latest Met Office Global Coupled model, GC5 (HadGEM3-GC5-LM), with fixed year 2000 control atmospheric composition. The ocean and sea ice components are on a 1/4° grid (eORCA025) with 75 vertical levels varying from 1m at the surface to 200m at depth. The atmosphere and land components are at a resolution of N96 (approximately 130 km) with 85 hybrid vertical levels. The model simulations were run on the Monsoon2 Met Office collaborative platform (Cray XC-40) using Rose/Cylc7 software and a Cray FORTRAN compiler. The archived model outputs 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 which were used to estimate the total diapycnal mixing. The outputs were generated by originators at the National Oceanography Centre Southampton and the Met Office under the Marine LTSS: Climate Linked Atlantic Sector Science (CLASS) project funded by the Natural Environment Research Council (NERC) under reference NE/R015953/1.
