Seasonal variation of daily total column ozone (TCO) and role of its depletion and formation rate on surface temperature over Dumdum at Kolkata, India

Abstract

The purpose of the paper is to present the variation of total ozone concentration over Dumdum at Kolkata, India during different seasons. It is concluded that the trend of ozone concentration during different seasons are different. A critical analysis is done and following important results are obtained. (i)The total ozone concentration increases during the pre-monsoon and winter periods. During premonsoon period rate of formation of ozone increases sharply with the rise of surface temperature.(ii) TCO decreases during the monsoon and post-monsoon periods, throughout the period of study. During monsoon period rate of depletion of ozone increases and during post-monsoon period rate of depletion of ozone decreases with the increase of temperature.(iii) Possible explanations are also presented.

Effect of cloud on atmospheric ozone formation over Hyderabad (17.27°N, 78.28°E), India

“…Stations over Southern Peninsula and over the lower Ganga valley had been found to exhibit at decreasing trend at same level of significance. The studies of ozone layer is different parts of the world have been reported [8][9][10][11] Monod and Carlier [12] performed a box model study of the multiphase photochemistry (both gas and aqueous phases) of C 1 organic compounds within a non-precipitating cloud on a local scale. They found that in a situation where ozone accumulates in clear sky conditions, as soon as cloud is formed, the tropospheric ozone estimate changes drastically; the net production decreases by a factor of 2 or more and depending on the NOx concentration and the pH values, can actually lead to chemical destruction.…”

Planar atmospheric pressure dielectric barrier discharge for ozone production

“…Ozone can be used for bacterial sterilization [16], purifying drinking water systems instead of the chlorine [17] with the advantage of ozone does not form organo-chlorine compounds, and does not remain in the water after treatment, once it has decayed; it leaves no taste or odor in drinking water. It has diverse effect in atmosphere [18][19][20].…”

Changes in tropospheric ozone concentration over Indo-Gangetic Plains: the role of meteorological parameters

“…It is greatly influenced by predominant meteorological conditions (temperature, solar flux, wind speed and relative humidity). Several authors have studied the possible interaction of surface temperature and cloud cover on ozone concentration (Liu et al 2006 ; Voulgarakis et al 2009 ; Jana et al 2010 , 2011 ; Midya et al 2011 ; Ghosh et al 2015 ). O 3 concentration increases with an increase in solar flux and temperature (Gorai et al 2015 ).…”
