Short summary
We develop a computationally efficient space-based top-down method to inverting NOx emissions in major urban areas at high resolution. The inversion method uses long-term OMI NO2 data to enhance the horizontal resolution, and it accounts for the nonlinear effects of horizontal transport, chemical loss, and deposition on NOx. The inversion results reveal fine-scale spatial information of emissions which is hardly captured by bottom-up inventories.
