In this study, the vertical distributions of optical turbulence at the Peak Terskol observatory (43.27472\u00b0N 42.50083\u00b0E, 3127 m a.s.l.) using the Era-5 reanalysis and scintillation measurements are investigated. For the closest reanalysis grid node to the observatory, vertical profiles of the structural constant of the air refractive index turbulent fluctuations Cn2 were obtained. The calculated Cn2(z) vertical profiles are compared with the vertical distribution of turbulence intensity obtained from tomographic measurements with a Shack\u2013Hartmann sensor. The atmospheric coherence length at the location of Terskol Peak was estimated. Using a combination of atmospheric models and paramaterization schemes of turbulence, Cn2(z) profiles at Mt. Kurapdag were obtained. The values of atmospheric coherence length at Peak Terskol are compared with estimated values of this length at the ten astronomical sites, including Ali, Lenghu and Daocheng.<\/jats:p>","DOI":"10.3390\/rs16122102","type":"journal-article","created":{"date-parts":[[2024,6,11]],"date-time":"2024-06-11T03:15:58Z","timestamp":1718075758000},"page":"2102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Vertical Distribution of Optical Turbulence at the Peak Terskol Observatory and Mount Kurapdag"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1682-8182","authenticated-orcid":false,"given":"Artem Y.","family":"Shikhovtsev","sequence":"first","affiliation":[{"name":"Institute of Solar-Terrestrial Physics SB RAS, Lermontov St. 126a, 664033 Irkutsk, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2456-1366","authenticated-orcid":false,"given":"Chun","family":"Qing","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2689-3383","authenticated-orcid":false,"given":"Evgeniy A.","family":"Kopylov","sequence":"additional","affiliation":[{"name":"Institute of Astronomy, Russian Academy of Sciences, Leninsky Prospekt 14, 119017 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6710-7468","authenticated-orcid":false,"given":"Sergey A.","family":"Potanin","sequence":"additional","affiliation":[{"name":"Institute of Astronomy, Russian Academy of Sciences, Leninsky Prospekt 14, 119017 Moscow, Russia"},{"name":"Faculty of Physics, Lomonosov Moscow State University, Leninskie Gory 1, 119991 Moscow, Russia"},{"name":"Sternberg Astronomical Institute, Lomonosov Moscow State University, Universitetskii Ave. 13, 119234 Moscow, Russia"}]},{"given":"Pavel G.","family":"Kovadlo","sequence":"additional","affiliation":[{"name":"Institute of Solar-Terrestrial Physics SB RAS, Lermontov St. 126a, 664033 Irkutsk, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1146\/annurev.aa.23.090185.000315","article-title":"Fundamental and applied aspects of astronomical \u201cseeing\u201d","volume":"23","author":"Coulman","year":"1985","journal-title":"Annu.
