Due to the implementation of air pollution control measures in China, quality has significantly improved, although there are still additional issues be addressed. This study used long-term trends pollutants discuss achievements and challenges further improving China. The Kolmogorov-Zurbenko (KZ) filter multiple-linear regression (MLR) were quantify meteorology-related emission-related from 2014 2022 KZ analysis showed that PM2.5 decreased by 7.36 ± 2.92 % yr−1, while daily maximum 8-h ozone (MDA8 O3) an increasing trend with 3.71 2.89 yr−1 decrease increase MDA8 O3 primarily attributed changes emission, relative contribution 85.8% 86.0%, respectively. Meteorology variations, including increased ambient temperature, boundary layer height, reduced humidity, also contributed reduction enhancement O3. exhibited continuous increase, respectively, 2022, variation rates slowed during 2018-2020 compared 2014-2017, highlighting quality, particularly simultaneously reducing recommends NH3 emissions agriculture sector rural areas transport urban levels. Addressing requires precursor gases based on site-specific atmospheric chemistry considerations.

Air pollution is influenced by a combination of pollutant emissions and meteorological conditions. Anthropogenic conditions are the two main causes atmospheric pollution, contribution meteorology to reduction PM2.5 concentrations across country has not yet been comprehensively examined. This study used Kolmogorov–Zurbenko (KZ) filter random forest (RF) model decompose reconstruct time series in five major urban agglomerations China, analyzing impact factors on concentrations. From 2015 2021, significantly decreased all agglomerations, with annual averages dropping approximately 50% Beijing–Tianjin–Hebei (BTH), Yangtze River Delta (YRD), Pearl (PRD), Central Plain (CP), Chengdu–Chongqing (CC). was due both favorable emission reductions. The KZ effectively separated series, RF achieved high squared correlation coefficient (R2) values between predicted observed values, ranging from 0.94 0.98. Initially, had positive reduction, indicating unfavorable conditions, but this gradually turned negative, By rates BTH, YRD, PRD, CP, CC changed 14.3%, 16.9%, 7.2%, 12.2%, 11.5% −36.5%, −31.5%, −26.9%, −30.3%, −23.5%, respectively. Temperature pressure most significant effects decline BTH CP after 2017 indicated that control measures were taking effect. confirms effective combined jointly contributed improvement air quality.
