Short summary
We present a timely analysis of the effects of the recent lockdown in Shanghai on ground-level ozone (O3). Despite a huge reduction in human activity, O3 concentrations frequently exceeded the O3 air quality standard during the 2-month lockdown, implying that future emission reductions similar to those that occurred during the lockdown will not be sufficient to eliminate O3 pollution in many urban areas without the imposition of additional VOC controls or substantial decreases in NOx emissions.
