Ozone if formed usually when UV rays hit Oxygen(O2), and if forms protective ozone layer high up in atmosphere. But ground level ozone like this are formed from other pollutants in the presence of sunlight. That is factory and vehicle's pollutants react on sunlight and creates ozone which is harmful
