Abstract

Changes in the atmospheric electricity characteristics (AECs) during the spring of 2020 in the urban, suburban, and very low human impact areas (Irkutsk, Irkutsk oblast; Voeikovo, Leningrad oblast; Tiksi, Republic of Sakha) are considered. Based on the AEC data, a theoretical assessment of the change in aerosol concentrations at these sites was carried out. Apparently, the decline in economic activity associated with the measures to prevent the expansion of COVID-19 significantly decreased the concentration of airborne particles in cities and suburban regions.

2020年春季经济活动下降期间不同地理区域大气电特征变化

摘要

考虑了 2020 年春季城市、郊区和人类影响极低的地区（伊尔库茨克州伊尔库茨克州；列宁格勒州沃伊科沃州；萨哈共和国提克西）大气电力特性 (AEC) 的变化。根据 AEC 数据，对这些地点的气溶胶浓度变化进行了理论评估。显然，与防止 COVID-19 扩大的措施相关的经济活动下降显着降低了城市和郊区空气中颗粒物的浓度。
