Short summary
Though the Hong Kong government has made great efforts toward a reduction in emissions, ambient O3 levels have presented an increasing trend in the past decade. Data analysis and model simulations indicated that the locally produced O3 in Hong Kong varied by seasons, while regional transport from the PRD region made a substantial contribution to ambient O3 in Hong Kong and even increased in autumn. This long-term study has important implications for other Chinese cities to reduce O3 pollution.
