Coupled ensemble reforecasts using the ECMWF IFS cycle 47r3, configured as follows. The atmosphere is set up with 15 ensemble members, 137 model levels and run on Tco639 cubic octahedral reduced Gaussian grids. The IFS is coupled hourly to a 75-level NEMO v3.4 ocean model and an LIM2 sea ice model, both utilising the ORCA025 tripolar grid with a grid spacing of approximately 0.25 degrees. The ocean and atmosphere are fully coupled throughout the 46-day forecast, producing output every 12 hours. Fifteen reforecasts are used.

Forecasts using IFS EPS CY47R3 replicating operations (51 members, TCo639, ORCA025Z75). The ocean state has had a hydrostatically balanced estimate of anthropogenic influence (warming) since 1850-1900 added, such that the total anthropogenic influence is twice estimated at the present day (an equal but opposite perturbation to expid b2nn). The CO2 concentration was set to 625 ppm.
