Short summary

We use a newly built two-way coupling system of the GEOS-Chem CTM to simulate the global tropospheric O₃ in 2009. It significantly improves the simulation upon the global model by comparisons with a suite of ground, aircraft, and satellite measurements, also reduces the global OH by 5 % with enhancements by 5 % in the lifetimes of MCF and methane. Therefore, improving model representations of small-scale processes is a critical step forward to understanding the global tropospheric chemistry.
