Abstract:

{E}thylene, representative of volatile organic compounds and high photochemical ozone creation potential precursor, has been monitored with a single-ended CO₂-TEA laser-based DIAL system using a topographic target. A correlation between ozone concentration and ethylene evolutions in Madrid's urban atmosphere was demonstrated and supported with a basic photochemical smog model. The present work brings additional evidence to the many models which state that ethylene, being a hydrocarbon, has a role to play in the generation of tropospheric ozone.
