Short summary

We investigated the impact of spatial proxies on the representation of gridded emissions by comparing six gridded NO_x emission datasets over China developed from the same magnitude of emissions and different spatial proxies. GEOS-Chem-modeled NO₂ columns from the six gridded emissions are compared with satellite-based columns from OMI. Results show that differences between modeled and satellite-based NO₂ columns are sensitive to the spatial proxies used in the gridded emission inventories.
