The relationship between electric field variations and microparticle concentrations in the atmospheric surface layer has been studied using the example of the Moscow region. Synchronous field observations of the electric field strength obtained at two stations (the Moscow Center of Geophysical Monitoring and the Mikhnevo Geophysical Observatory of the Institute of Geosphere Dynamics, Russian Academy of Sciences) have been used. Under megacity conditions, the amplitudes of electric field signals have been found to increase relative to their values outside the region. The ratios of average electric field strengths at the observation stations to the values obtained outside the region have been estimated using the model that is developed. Variations in the electric field have been compared with changes in the concentrations of CO, NOx, SO2, and fine particulate matter (PM2.5 and PM10); the electric field strength and the concentration of microparticles under megacity conditions have been found to be correlated.

大城市气溶胶污染和大气电场干扰

以莫斯科地区为例，研究了大气表层中电场变化与微粒浓度之间的关系。已经使用了在两个站（莫斯科地球物理监测中心和俄罗斯科学院地球圈动力学研究所的米赫涅沃地球物理观测站）获得的电场强度的同步现场观测。在大城市条件下，已发现电场信号的幅度相对于区域外的值增加。观测站的平均电场强度与区域外获得的值的比率已使用开发的模型进行估计。电场的变化与 CO、NOx、SO2、和细颗粒物（PM2.5 和 PM10）；已发现大都市条件下的电场强度和微粒浓度是相关的。
