The region is located at a considerable distance (500 km) from the nearest AERONET station; therefore, previous atmospheric data were not available. As a solution, the in situ self-measured aerosol optical depth (AOD) and Angstr\u00f6m exponent, as well as satellite products (MAIAC and CALIPSO) for MODIS data, were used. This allowed us to set background values of an AOD of 0.11 at a wavelength of 500 nm and an Angstr\u00f6m exponent of 1.2, against their maximum values of 0.38 and 2.5, respectively. To explain these variations, the registered conditions and the microstructure of the dust aerosol over the studied region are presented. For days with background values, the analysis of the particle size distribution data did not show a predominance of any particle size. The optical properties of a smoke aerosol in an atmospheric column are described, and an analysis of the dynamics of particle size variability is presented. A comparative analysis of the optical characteristics of atmospheric aerosol over the Gorky and Cheboksary Reservoirs using in situ and MODIS products was carried out.<\/jats:p>","DOI":"10.3390\/rs15235455","type":"journal-article","created":{"date-parts":[[2023,11,22]],"date-time":"2023-11-22T08:47:43Z","timestamp":1700642863000},"page":"5455","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Spatio-Temporal Variability of the Aerosol Optical Depth over the Gorky and Cheboksary Reservoirs in 2022\u20132023"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4007-6977","authenticated-orcid":false,"given":"Darya","family":"Kalinskaya","sequence":"first","affiliation":[{"name":"Radiophysical Department, Lobachevsky State University of Nizhny Novgorod, 23 Gagarin Avenue, Nizhny Novgorod 603022, Russia"},{"name":"Marine Hydrophysical Institute of the Russian Academy of Sciences, 2 Kapitanskaya St., Sevastopol 299011, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8550-2418","authenticated-orcid":false,"given":"Aleksandr","family":"Molkov","sequence":"additional","affiliation":[{"name":"Radiophysical Department, Lobachevsky State University of Nizhny Novgorod, 23 Gagarin Avenue, Nizhny Novgorod 603022, Russia"},{"name":"Institute of Applied Physics of the Russian Academy of Sciences, 46 Ulyanov St., Nizhny Novgorod 603950, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,22]]},"reference":[{"key":"ref_1","first-page":"41","article-title":"Results of coal research in order to reduce emissions of pollutants.
