Figure 2-2: In the stratosphere, NO x both catalytically destroys ozone and acts to interfere with the destruction of
ozone by reactions of HO x and halogens. Shown is a calculation of the rate of ozone loss in the lower
stratosphere for springtime mid-latitude conditions during March. The loss from each family is illustrated. Ozone
loss in the lowermost stratosphere is quite slow (a few percent per month). The right panel shows the effect on
the removal rate of ozone when 20% more reactive nitrogen is added to the stratosphere uniformally (calculations
provided by R. Salawitch using 1D-trajectory model).
