A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. Even though the CO 2 enhancements over background were comparable in the two years, about 25 ppm in 2002 and 35 ppm in 2010, the ?CO/?CO2 CO2 ratio for this flight track segment decreased from 24.5
