Abstract

We analyzed the spatial distribution and temporal variation trend of tropospheric NO₂ over Guangdong-Hong Kong-Macao Greater Bay Area (GBA) using the satellite retrieved data from the Ozone Monitoring Instrument (OMI) sensor, and the influencing factors for these temporal-spatial characteristics. The results showed that the tropospheric NO₂ decreased by about 2.8% per year from 2005 to 2018 over GBA. The wavelet coefficients showed that there was a 9 months of main oscillation period and the higher and lower concentration appeared in winter and summer, respectively. Due to the effects of anthropogenic emissions and various natural factors, the monthly variation of the tropospheric NO₂ was significantly different in time and space over GBA. The minimum and maximum values appeared in June and December, respectively, and the multi-years mean values were 3.9665×10¹⁵ and 12.3423×10¹⁵ molec/cm². The tropospheric NO₂ showed obvious spatial heterogeneity characteristics, the most obvious heterogeneity was in December. The high-value areas with serious NO₂ pollution over GBA were mainly found in the central region, such as Guangzhou, Foshan and Zhongshan cities. The maximum tropospheric NO₂ column density was up to 18.8306×10¹⁵molec/cm². It was about three times that of the surrounding areas, and the high-pollution gradually extended around areas. The low-value areas were mainly in northern Zhaoqing City and eastern Huizhou City, and the average tropospheric NO₂ concentration was about 7.1400×10¹⁵molec/cm². The growth rates showed a significant difference over GBA. The tropospheric NO₂ column density varies from -15×10¹⁵ to 6×10¹⁵molec/cm², and the growth rates from -65% to 65%. The increased areas occurred in northern Zhaoqing City and the eastern Huizhou city. The larger reduced were concentrated in the high value areas in the middle, and the largest reduced were the junction of Guangzhou City, Foshan City and Zhongshan City.
