Short summary

We implement a new 12-km global nested simulation capability in GEOS-Chem, an open-source global 3-D model of atmospheric chemistry. Compared with the standard 25-km simulation, the 12-km simulation features stronger vertical transport due to better resolved horizontal convergence, along with improved representation of urban NO2 and ozone titration. Application to methane emission inversion yields higher information content and resolves finer spatial structure in emission sectors.
