Photochemical box model calculations constrained by observations of NOx, VOCs, O3 and other stable species indicate that the instantaneous ozone formation rate was much lower over downtown Houston than it was over the Ship Channel. The much faster O3 formation rates and higher concentrations observed over the Ship Channel are attributed to the much higher hydrocarbon reactivity, the majority of which was contributed by low molecular weight alkenes. These high hydrocarbon reactivities also caused O3 over the ship Channel to be produced with much higher efficiency than over urban Houston.
