摘要

本研究考察了印度德里高污染城市群大气氨(NH3)与其他痕量气体(一氧化氮、二氧化氮、二氧化硫和一氧化碳)的长期特性和关系。2011-2022 年期间,德里观测点记录了环境痕量气体(NH3、NO、NO2、SO2 和 CO)和气象数据。2011-2022 年期间,环境中的 NH3、NO、NO2、SO2 和 CO 的总体平均混合比分别为 18.9 ± 5.0 ppb、19.9 ± 4.8 ppb、19.1 ± 5.3 ppb、2.15 ± 0.38 ppb 和 1.47 ± 0.42 ppm。研究期间,除二氧化硫混合比外,NH3、NO、NO2 和 CO 的混合比均出现了明显的日变化和季节变化。在所有季节,痕量气体的混合比在夜间较高,在白天较低。相关分析表明,在德里的研究地点,较高的 NO、NO2 和 CO 负荷影响了 NH3 的混合比。

Long–Term Characteristics of Ambient Trace gases and Meteorology in Delhi, India

The present study examined the long–term characteristics and relationship of atmospheric ammonia (NH3) with other trace gases (NO, NO2, SO2 and CO) at highly polluted urban agglomeration of Delhi, India. Measurements of ambient trace gases (NH3, NO, NO2, SO2, and CO) and meteorology were recorded at the observational site of Delhi from 2011–2022. Overall mean mixing ratios of ambient NH3, NO, NO2, SO2 and CO were 18.9 ± 5.0 ppb, 19.9 ± 4.8 ppb, 19.1 ± 5.3 ppb, 2.15 ± 0.38 ppb, and 1.47 ± 0.42 ppm, respectively during 2011—2022. During study, a significant diurnal and seasonal variation in mixing ratios of NH3, NO, NO2, and CO were observed except SO2 mixing ratio. During all the seasons, the mixing ratios of trace gases were observed higher during nighttime and lower during daytime. Correlation analysis reveals that the higher loading of NO, NO2 and CO influenced the mixing ratio of NH3 at the study site of Delhi.
