Using airborne observations of hydrocarbon and related trace-gas species, we compare plume compositions over different parts of Houston, and to trace the source regions for high O3 plumes. Ozone formation over eastern Houston was found to be very rapid (up to 140 ppb/hr) with very efficient ozone production efficiencies (up to 28) driven by the high concentrations of reactive hydrocarbons emitted by industries in eastern Houston.
