摘要：Analysis of total ozone column at Dumdum (22.5oN, 88.5oE), India during, before and after Diwali reveals an elevation in total ozone during Diwali and after few days for the period 2000-2010 due to spontaneous bursts in the absence of sunlight - namely, the exuberant mass of colour emitting sparklers which are lit during the Diwali night festivities that occurred every year during October and November. During burning, a significant portion of the emitted light by the sparklers which is composed of an oxidizer (potassium nitrate, potassium chlorate or potassium perchlorate), a fuel, regulators and binders constitutes a wavelength below 240 nm that is enough to dissociate atmospheric molecular oxygen into atomic oxygen enabling the formation reaction of ozone to takes place.
