Abstract

Data on black carbon (BC) concentration C_BC in the air basin of Moscow, and 5-day back trajectories of air mass motion, obtained in the period of 2003–2014, were used to determine the dependence of variations in black carbon concentration in the air basin of Moscow on the direction of air mass transport, and to determine the black carbon source regions. The 12-year measurements of black carbon concentration in Moscow air are used to show that the С_BC variations are determined by the character of the air mass circulation in the troposphere. Measurements of black carbon content in the Moscow air basin in June–September 2019 and 10-day back trajectories of air mass transport were used to study the effect of the latter on the air pollution level in Moscow.

莫斯科大气中黑碳含量变化对航空运输方向的依赖性

摘要

莫斯科空气盆地中黑碳（BC）浓度C _BC的数据以及2003年至2014年期间获得的5天空气运动的后向轨迹，用于确定黑碳浓度变化的相关性。莫斯科的空气盆地将沿空气质量传输的方向，并确定黑碳源的地区。莫斯科空气中黑碳浓度的12年测量结果表明，_BC变化是由对流层空气质量循环的特征决定的。使用2019年6月至9月在莫斯科空气盆地中黑碳含量的测量值以及10天后气团运输的轨迹来研究后者对莫斯科空气污染水平的影响。
