Abstract

The results of lidar sensing of aerosol pollution in St. Petersburg (Russia) were compared with ones located in Minsk (Belarus) and Kuopio (Finland) to assess the impact of large cities on atmospheric pollution by aerosol particles. For comparison, aerosol optical depth (AOD) data obtained at the three stations from 2014 to 2021 were used. Lidar sounding of atmospheric aerosols was carried out using aerosol Nd:YAG lasers operating at three wavelengths: 355, 532 and 1064 nm. Due to differences in the lidar station equipment characteristics and, consequently, in the lower limit for determining aerosols, the aerosol optical depth was compared in the range of heights from 800 to 1600 m at 355 and 532 nm. Since the compared stations do not have data for all years, the period from 2014 to 2016 was analyzed separately. The average annual AOD 355 in Minsk in the period 2014-2016 is almost the same as the average annual AOD in St. Petersburg. When comparing data in St. Petersburg and Minsk for the period 2014-2020, AOD 355 in St. Petersburg exceeds AOD 355 in Minsk by 1.46 times. AOD 532 nm in Minsk is larger than in St. Petersburg, regardless of the chosen comparison period. The average annual AOT 355 in Kuopio is lower than in Minsk and St. Petersburg by 2.1 times, while at a wavelength of 532 nm they are 3.6 times lower than in Minsk and 2.6 times in St. Petersburg. The calculated Angstrom exponent coefficient shows that the coarse mode in Minsk is higher than in St. Petersburg. The atmosphere over Kuopio has a lower content of aerosol particles. Since 2017, there was a steady excess of aerosol content over St. Petersburg compared to Minsk. Additionally, a comparison of the lidar data with the total AOD of AERONET stations located in Kuopio, Minsk and Peterhof (25 km from the lidar station in St. Petersburg) was carried out. The AOD obtained by lidar and AERONET method is in good agreement.

以圣彼得堡（俄罗斯）、库奥皮奥（芬兰）和明斯克（白俄罗斯）的激光雷达传感数据为例研究大气气溶胶污染问题

将圣彼得堡（俄罗斯）的气溶胶污染激光雷达传感结果与明斯克（白俄罗斯）和库奥皮奥（芬兰）的气溶胶污染激光雷达传感结果进行了比较，以评估大城市气溶胶颗粒对大气污染的影响。比较中使用了这三个站点从 2014 年至 2021 年获得的气溶胶光学深度（AOD）数据。对大气气溶胶的激光雷达探测是使用气溶胶 Nd:YAG 激光器进行的，该激光器有三种波长：355、532 和 1064 nm。由于激光雷达站的设备特性不同，因此确定气溶胶的下限也不同，气溶胶光学深度是在波长为 355 和 532 nm 的 800 至 1600 米高度范围内进行比较的。由于所比较的站点没有所有年份的数据，因此对 2014 年至 2016 年期间的数据进行了单独分析。2014-2016 年期间，明斯克的年平均 AOD 355 与圣彼得堡的年平均 AOD 几乎相同。在比较圣彼得堡和明斯克 2014-2020 年的数据时，圣彼得堡的 AOD 355 比明斯克的 AOD 355 高出 1.46 倍。明斯克的 AOD 532 nm 大于圣彼得堡，与所选的比较期无关。库奥皮奥的年平均 AOT 355 值比明斯克和圣彼得堡低 2.1 倍，而波长为 532 nm 的年平均 AOT 355 值比明斯克低 3.6 倍，比圣彼得堡低 2.6 倍。计算得出的安氏指数系数显示，明斯克的粗模高于圣彼得堡。库奥皮奥上空的大气中气溶胶粒子含量较低。自 2017 年以来，圣彼得堡上空的气溶胶含量一直高于明斯克。此外，还将激光雷达数据与位于库奥皮奥、明斯克和彼得霍夫（距离圣彼得堡激光雷达站 25 公里）的 AERONET 站的总 AOD 进行了比较。通过激光雷达和 AERONET 方法获得的 AOD 非常吻合。

期刊介绍： Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is founded by the Faculty of Geography of Lomonosov Moscow State University, The Russian Geographical Society and by the Institute of Geography of RAS. It is the official journal of Russian Geographical Society, and a fully open access journal. Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” publishes original, innovative, interdisciplinary and timely research letter articles and concise reviews on studies of the Earth and its environment scientific field. This goal covers a broad spectrum of scientific research areas (physical-, social-, economic-, cultural geography, environmental sciences and sustainable development) and also considers contemporary and widely used research methods, such as geoinformatics, cartography, remote sensing (including from space), geophysics, geochemistry, etc. “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is the only original English-language journal in the field of geography and environmental sciences published in Russia. It is supposed to be an outlet from the Russian-speaking countries to Europe and an inlet from Europe to the Russian-speaking countries regarding environmental and Earth sciences, geography and sustainability. The main sections of the journal are the theory of geography and ecology, the theory of sustainable development, use of natural resources, natural resources assessment, global and regional changes of environment and climate, social-economical geography, ecological regional planning, sustainable regional development, applied aspects of geography and ecology, geoinformatics and ecological cartography, ecological problems of oil and gas sector, nature conservations, health and environment, and education for sustainable development. Articles are freely available to both subscribers and the wider public with permitted reuse.
