| Abstract: | To study the pollution distribution of ozone in Xuchang, this paper analyzed the 2014-2016 monitoring data of 3 national air monitoring stations in Xuchang. The results showed:the ozone pollution of Xuchang was getting worse in 2014-2016, where in 2016 the most serious pollution happened. Ozone concentrations inXuchang had obvious seasonal characteristics. The most serious pollution appeared in late spring and summer. The diurnal variation of ozone, nitrogen dioxide, nitric oxide and ni-trogen oxideconcentrations in different seasons were not the same, and the ozone also had obvious diurnal variation, which showed a single peak distribution, maximum occurred during the day around 14:00~15:00. Ozone and nitrogen dioxidehave a good cor-relation. |
