Summary, etc. |
<p>Continuous measurements of the surface ozone (O<sub>3</sub>), oxidess of nitrogen (NO<sub>x</sub>), carbon monooxide (CO), methane (CH<sub>4</sub>) and total non-methane hydrocarbons (TNMHCs) have been carried out at an urban site of Delhi, India during 1–31, May 2014 to study the influence of ozone precursors (NO<sub>x</sub>, CO, CH<sub>4</sub> and TNMHCs) in the formation of surface O<sub>3</sub> over Delhi. In the present study, the average mixing ratios of surface O<sub>3</sub>, NO, NO<sub>2</sub>, CO, CH<sub>4</sub> and NMHCs were recorded as 37.1 ± 9.8 ppb, 20.4 ± 13.1 ppb, 14.7 ± 3.2 ppb, 1.4 ± 0.5 ppm, 2.6 ± 0.4 ppm and 0.13 ± 0.09 ppm, respectively. The surface O<sub>3</sub>, NO, NO2, CO, CH<sub>4</sub> and TNMHCshave shown the prominent diurnal variations during study. The result reveals that the surface O<sub>3</sub> positively correlated with NO<sub>2</sub>, TNMHCs, NO<sub>2</sub>/NO and NMHCs/NO<sub>x</sub> and influenced the surface O<sub>3 </sub>production at the observational site of Delhi.</p><p> </p><p> </p><p> </p> |
