Fig. 5. NOx emissions, lifetime, and predicted column mass for 12 United States cities.

Fig. 5.

(A) MOVES NOx emissions for the core county of each of the 12 cities shown. (B) Lifetimes for the same 12 cities fit from BEHR line densities. (C) NOx mass predicted for 12 cities as the product of their lifetime and MOVES NOx emissions. (D) Trends in average NO2 VCDs and MOVES NOx emissions compared with the average predicted NOx mass for the 12 cities in (C). Each series in (D) is normalized to its average.
