Downstream HO2S Graph Line Example 1
Equation
RATIO = 26 inversions (upstream HO2S inversions) divide 7 inversions (downstream HO2S inversions) = 3.7 (good WU-TWC)
Scheme 46
Scheme 47
Downstream HO2S Graph Line Example 3
Equation
RATIO = 26 inversions (upstream HO2S inversions) divide 19 inversions (downstream HO2S inversions) = 1.4 (deteriorated WU-TWC)
