Short summary

Limited by coarse resolutions, global chemical transport models cannot well capture small-scale nonlinear processes. To alleviate the problem, we develop a two-way coupled system to integrate the global GEOS-Chem model and its three high-resolution nested models covering Asia, Europe and North America. Confirmed by comparisons with observations, the coupled system improves upon the global model with a 10% increase in global tropospheric CO, a 4% decrease in OH and a 4% increase in MCF lifetime.
