Using the stated loss ratio

L_{N} = 3 L_{C}

in the derived logarithmic sensitivity gives

\frac{d ln [ O _{3} ]}{d ( T ^{- 1} )} = \frac{2610 + 3 ( 1200 )}{2 + 3} = 1242 K .

The positive sign means that cooling, which increases

T^{- 1}

, increases the steady ozone concentration within this restricted middle-stratosphere model.
