Delhi city is not only the country’s capital but is also one of the top most polluted cities of the world. In this regard, pollution is discussed as a problem in a number of ways, but the pollutant is not much discussed of. The secondary pollutant of Ozone is also not much observed in literature. Ozone is a naturally occurring gas in the atmosphere but is also formed due to human activities which are generally related to the emission of nitrogen and its compounds. In this regard, the study of human activity becomes very important. The time period offered by COVID 19 provides a significant window to study pollution in ways more than one. The current study observes the relationship between Ozone and Nitrogen dioxide taking Nitrogen Dioxide as an Ozone precursor. Results indicate that Nitrogen Dioxide does not indicate any relationship with Ozone for the city.
