Abstract Ground-level ozone exceedances in industrial parks remain poorly understood, as the drivers identified for urban atmospheres have rarely been quantified at the precursor levels typical of these parks. We analyzed a 56-day record of hourly observations from six monitoring sites in a fine-chemical industrial park on Hangzhou Bay, eastern China, and contrasted an eight-day ozone exceedance episode that emerged in early September 2020 with eight non-exceedance control days.
