Short summary
                    This study shows that there were often co-occurrences of high PM2.5  and O3 concentrations, which were related to high HONO, in eastern China. This result suggests that high daytime HONO can be photodissociated to OH radicals, enhancing the chemical production of O3 and suggesting that under high aerosol conditions, the chemical oxidizing process for O3 production can occur in eastern China.
