Abstract

The paper analyzes the trends in the average monthly concentrations of nitrogen dioxide in the period from 2005 to 2021 in 18 large cities in different geographical areas: St. Petersburg, Moscow, Kyiv, Donetsk, Helsinki, Warsaw, Istanbul, Athens, Rome, Milan, Barcelona, Madrid, Paris, London, and Amsterdam. It was found that, in all cities, the concentration of this gas decreases, but at different rates. The highest rate of change was recorded in cities with the highest gas content at the time of the initial stage—2005. A linear dependence of the average nitrogen dioxide concentration on the population and anthropogenic emissions was revealed according to HTAPv3 data. Approximately every 1 million people of the population of large cities is responsible for the formation of a gas concentration of ∼200 × 10¹⁵ molecules/cm², regardless of the geographical location of the city. Every ∼10 000 t/month of nitrogen dioxide emissions based on HTAPv3 generate gas concentrations of ∼500 × 10¹⁵ molecules/cm². Using these dependences, it is possible to estimate anthropogenic emissions of NO₂ sources throughout the country, based on remote sensing data. The results of the study also indicate the possibility of verifying and correcting inventory databases of gas emissions based on satellite observations of the nitrogen dioxide content in the atmosphere.

利用卫星数据监测欧洲和俄罗斯城市大气中的二氧化氮含量

摘要本文分析了 2005 年至 2021 年期间不同地理区域 18 个大城市二氧化氮月平均浓度的变化趋势：圣彼得堡、莫斯科、基辅、顿涅茨克、赫尔辛基、华沙、伊斯坦布尔、雅典、罗马、米兰、巴塞罗那、马德里、巴黎、伦敦和阿姆斯特丹。研究发现，在所有城市中，这种气体的浓度都在下降，但下降的速度不同。在 2005 年初始阶段，气体含量最高的城市的变化率最高。根据 HTAPv3 数据，二氧化氮平均浓度与人口和人为排放量呈线性关系。无论城市的地理位置如何，大城市中大约每 100 万人口就会形成 200 × 1015 个分子/平方厘米的气体浓度。根据 HTAPv3，每 ∼10 000 吨/月的二氧化氮排放会产生 ∼500 × 1015 个分子/平方厘米的气体浓度。利用这些相关性，可以根据遥感数据估算出全国范围内的人为二氧化氮排放源。研究结果还表明，有可能根据大气中二氧化氮含量的卫星观测结果对气体排放清单数据库进行核实和修正。
