Control Simulation

The IFS-NEMO control simulation covers 11 years in total (1990-2000) and helps to address whether the historical simulation starts close to equilibrium. The atmospheric component IFS used a horizontal resolution of 5km (TCo2559 grid) while the ocean and sea ice components NEMO and SI3 used a resolution of 10 km (eORCA12 grid).

The simulation was conducted in two stages in MN5, as indicated in the table.

Forcing data

In this control simulations all external radiative forcings, including greenhouse gases, ozone, and aerosol concentrations were kept constant at year 1990 levels.
