Abstract

CO₂-laser DIAL ozone integrated measurements were performed in Madrid City. The results showed a dependence of ozone on UVB radiation, abundance of vehicle generated NO_X's and hydrocarbons. An average decrease of 12.0 ± 1.2 % of the intensity of vehicle traffic resulted in a lowering the ozone load by almost 14.0 ±1.4 %. Moreover, measurements of atmospheric ethylene, as a hydrocarbon representative and its relation with ozone, were performed. Ozone showed the same behaviour namely, a slow increase then reached a maximum at around 15:00 and back to 40-50 ppb level. The new data can stimulate the development of new local models to understand the dynamic underlying urban pollution.
