    Comparing the Influences on NO<sub>2</sub> Changes in Terms of Inter-Annual and Seasonal Variations in Different Regions of China: Meteorological and Anthropogenic Contributions by Xuehui Bai, Yi Wang, Lu Gui, Minghui Tao, Mingyu Zeng

    Published 2025-01-01
    “…This study employs Kolmogorov–Zurbenko (KZ) filtering and stepwise multiple linear regression to isolate the effects of meteorological conditions on tropospheric NO<sub>2</sub> vertical column densities. Long term trends indicate an overall decline, with anthropogenic contribution rates exceeding 90% in Shanghai, Changchun, Urumqi, Shijiazhuang, and Wuhan, where interannual variations are primarily driven by human emissions. …”
