We develop a computationally efficient space-based top-down method to inverting NO〈sub〉〈i〉x〈/i〉〈/sub〉 emissions in major urban areas at high resolution. The inversion method uses long-term OMI NO〈sub〉2〈/sub〉 data to enhance the horizontal resolution, and it accounts for the nonlinear effects of horizontal transport, chemical loss, and deposition on NO〈sub〉〈i〉x〈/i〉〈/sub〉. The inversion results reveal fine-scale spatial information of emissions which is hardly captured by bottom up inventories.
