Additionally, the ν2 vibrational-rotational bands were recorded between 550 and 880 cm−1 using a classical glowbar source that made it possible to extend and refine information compared to published data on the observed transitions of these bands. The analyses of recorded spectra permitted us to deduce experimental set of energy levels for the ground (000) and the first bending (010) vibrational states, which significantly exceeds literature data in terms of rotational quantum numbers. For both isotopic species, the weighted fits of all experimental line positions were carried out including previously published microwave data. As a result of this work, the improved values of rotational and centrifugal distortion parameters for the states (000) and (010) were obtained that permitted modelling the experimental line positions with a weighted standard deviation of 1.284 (2235 transitions) and 0.908 (4597 transitions), respectively, for 16O16O18O, and 1.168 (824 transitions) and 1.724 (2381 transitions) for 16O18O16O.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1024856024700167.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141547586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High concentrations of submicron and absorbing (eBC) aerosol are pronounced in the average spatial distribution in the southwestern part of the Kara Sea, and they are minimal in the northern part. The difference in the average Vf and еВС between these regions is 30–60%. The average aerosol characteristics for the entire Kara Sea are: the atmospheric AOD (0.5 μm) is 0.043 with an Ångström exponent of 0.8, еВС = 22.8 ng/m3, Vf = 0.26 μm3/cm3, and Vс = 1.39 μm3/cm3.

Experimental results of sounding mesoscale Kelvin–Helmholtz waves by turbulent lidars in a stably stratified boundary layer of the atmosphere are presented. This paper presents the data of measurements by the BSE-4 lidar (532 nm), which has been working over forest-steppe for a long time. Atmospheric waves in most cases were observed in the evening and at night in the range of heights from the land to 600 m, when the Richardson number in the surface air layer did not exceed a critical value of +1/4. Fourier analysis of the time series of the structural characteristic of the refractive index (C_{n}^{2}) shows that the spectrum of the wave process in the atmospheric boundary layer consists of a set of monochromatic waves with different oscillation frequencies. During the observations, the period of the waves varied from 1 to 11 min, and their amplitude changed from 20 to 300 m. It is found that monochromatic waves exist from half an hour to two hours. The disappearance of some monochromatic waves is compensated by the appearance of new ones. The process of generating small-scale turbulence runs throughout the life cycle of a Kelvin–Helmholtz wave. The experimental results indicate that the turbulent lidar is a sensitive device ensuring remote detection and observation of atmospheric waves.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ozone anomalies recur every five years on average. The last, record strong decrease of the ozone level in the stratosphere of the Arctic was recorded in March–April 2020. In February 2022, ozone destruction developed according to a scenario very similar to the anomaly of 2020. Like in 2020, in 2022 the ClO mixing ratio, which can be considered a reliable indicator of ozone destruction, strongly increased after the return of sunlight to the Arctic latitudes, but the subsequent ozone depletion process was halted by a sudden major stratospheric warming on March 20, 2022. In this work, we analyze the ozone destruction in 2020–2022 based on measurements of the total ozone content over 2003–2022 from the TEMIS service, profiles of the air temperature and ozone mixing ratio for 2005–2022 and of ClO mixing ratio for 2020–2022 from Aura MLS observations. The following sites are considered: Eureka, Canada; Ny-Ålesund, Norway; Thule, Greenland; and Resolute, Canada. A relationship is revealed between ozone and chlorine oxide contents. High coefficients of correlation between oscillations of the above parameters at about the same altitudes of their recording, as well as between the total O3 and ClO contents calculated from their profiles, indicate their close interrelation. Hence, the ClO concentration and total content can be used as indicators of ozone destruction in the Arctic stratosphere.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
