EC-Earth is a climate model that runs with the TM5 chemiscal core. It simulates a free running climate and the meteorological fields are coupled to TM5. This figure shows the zonal mean O3 mixing ratios in the reference EC-Earth simulation (top), the differences compared to the corresponding ERA- Interim TM5 simulation (middle), and the contribution from the stratospheric O3 tracer (O3S) to these differences (bottom) for boreal winter (left) and boreal summer (right).
