Ozone weekend effect in cities: Deep insights for urban air pollution control.

ABSTRACT: Studying weekend-weekday variation in ground-level ozone (O₃) allows one to better understand O₃ formation conditions, with a potential for developing effective strategies for O₃ control. Reducing inappropriately the O₃ precursors emissions can either produce no reduction or increase surface O₃ concentrations. This paper analyzes the weekend-weekday differences of O₃ at 300 rural and 808 urban background stations worldwide from 2005 to 2014, in order to investigate the O₃ weekend effect over time and assess the effectiveness of the precursors emissions control policies for reducing O₃ levels. Data were analyzed with the non-parametric Mann-Kendall test and Theil-Sen estimator. Rural sites typically did
