Nitrogen and oxygen dominate the atmosphere. Carbon dioxide is much more abundant than the trace gases carbon monoxide and ammonia; typical background CO also exceeds ammonia. Thus the intended background ordering is $N_2>O_2>CO_2>CO>NH_3$,**B**. Local concentrations near emission sources need not follow this general ordering.
