Data for the Diesel exhaust Drive Significant Missing OH Reactivity: Field Evidence from Shanghai Megacity

The shared dataset was the characterization of missing OH reactivity (OHR) along with the source apportionment of ROGs and missing OHR, focusing on the impacts of missing OHR on ozone production rate and NOx thresholds, including 4 tables.​
Table 1. Time series and diurnal patterns of OHRcal, OHRmeas, missing OHR, and the pie chart of different categories to the OHRmeas.
Table 2. Impacts of missing OHR on net ozone production rate and ozone formation sensitivity regime.
Table 3. Scatter plot​ of missing OHR with major tracers during the whole measurement period.
Table 4. The mass distributions of each species among these factors for missing OHR sources and ROGs sources.
