Figure 6. Chemistry measurements at Harris Road site for O3, NO, NOx, and the relatively inert species CO for four episode nights. Derived quantities are:

  • Ox, the sum of O3 and NO2, conserved during titration of O3 and NO
  • NOx/NOy ratio, large (>0.9) for freshly polluted air and small (<0.6) for aged emissions.
