Abstract

Microwave measurements of ozone were performed in the middle atmosphere over Apatity (67° N, 33° E) in winter 2022/2023, during a period of high solar activity in solar cycle 25, with the use of a mobile ozonometer with an operating frequency of 110.8 GHz. The device had a single-sideband noise temperature of 2500 K, which made it possible to measure variations in O₃ in the middle atmosphere with a 15-min resolution. The ozone vertical profiles at altitudes of 22–60 km were retrieved and compared with MLS/Aura satellite vertical profiles of ozone and temperature. The behavior of ozone in February–March 2023 is analyzed. Ozone variations took place during the sudden stratospheric warming (SSW) which occurred in mid-February and was accompanied by an extraordinary increase in the total ozone content (TOC) from 240 to 500 DU. The limits of ozone variations at altitudes of 25, 40, and 60 km are given. The effect of the strong geomagnetic disturbance (storm), which took place on March 23–24, on the daily variations in ozone at an altitude of 60 km is discussed.

2023年2 - 3月极地大气平流层和中间层臭氧动力现象

利用工作频率为110.8 GHz的移动式臭氧计，于2022/2023年冬季在Apatity（67°N, 33°E）上空的中部大气中进行了臭氧的微波测量。该装置的单边带噪声温度为2500 K，这使得以15分钟的分辨率测量中部大气中O3的变化成为可能。反演了22 ~ 60 km的臭氧垂直剖面图，并与MLS/Aura卫星的臭氧和温度垂直剖面图进行了比较。分析了2023年2 - 3月臭氧的变化规律。臭氧变化发生在2月中旬发生的平流层突然变暖（SSW）期间，并伴随着总臭氧含量（TOC）从240 DU急剧增加到500 DU。给出了在海拔25km、40km和60km处臭氧变化的极限。讨论了3月23日至24日发生的强地磁扰动（风暴）对60km高空臭氧日变化的影响。

期刊介绍： Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
