Spatiotemporal distribution of ground-level ozone in China at a city level.

ABSTRACT: In recent years, ozone (O₃) pollution in China has shown a worsening trend. Due to the vast territory of China, O₃ pollution is a widespread and complex problem. It is vital to understand the current spatiotemporal distribution of O₃ pollution in China. In this study, we collected hourly data on O₃ concentrations in 338 cities from January 1, 2016, to February 28, 2019, to analyze O₃ pollution in China from a spatiotemporal perspective. The spatial analysis showed that the O₃ concentrations exceeded the limit in seven geographical regions of China to some extent, with more serious pollution in North, East, and Central China. The O₃ concentrations in the eastern areas were usually higher than those in the western a
