Extended Data Fig. 1: Time series and interannual trends of MDA8 ozone concentrations for East China during 2010–2012, 2013–2017 and 2018–2021 for urban (a) and rural areas (b).
From: Sustained emission reductions have restrained the ozone pollution over China
The smooth grey lines and dotted purple lines represent time series of predicted and observed MDA8 ozone averaged for each month, respectively. The black, blue and red lines represent the linear trends of MDA8 ozone for 2010–2012, 2013–2017 and 2018–2021, respectively. The annual variation rates (μg/m3/yr) during different periods, with significance levels (*p < 0.05) are presented (The numbers in the parentheses indicate the relative annual variation rate (%/yr)). Summer indicates June-August and winter indicates December-February.
