Conclusion: The results show that ozone concentration in Delhi is correlated with solar radiation, temperature, relative humidity and NOx concentration. No correlation was found with wind speed and PM2.5 concentration. Study also found that instances of high ozone pollution are distributed throughout the year (only exception being rainy days during the monsoon season) in Delhi and it is not only a summer season phenomena as generally believed.
Study findings reveal that efforts to tackle ozone pollution which are currently concentrated in summer need to expand to the whole of the year. Model developed in the study be used to forecast highly ozone formation by CPCB to issue health alerts.
