Short summary

We use three satellites measuring carbon dioxide (CO₂), carbon monoxide (CO) and nitrogen dioxide (NO₂) to calculate atmospheric enhancements of these gases from 27 urban areas. We calculate enhancement ratios between the species and compare those to ratios derived from four globally gridded anthropogenic emission inventories. We find that the global inventories generally underestimate CO emissions in many North American and European cities relative to our observed enhancement ratios.
