Abstract

The importance of controlling total ozone (TO) and surface ultraviolet irradiance is a reason for continuous monitoring of the ozonosphere using various ground-based and satellite methods and instruments. The global monitoring of TO has been carried out with the Russian instrument IKFS-2 on the Meteor-M No. 2 satellite since 2015. These measurements are conducted during the whole day and in polar night conditions. The developed algorithm based on using artificial neural networks and OMI satellite instrument measurements is periodically updated and allows determining TO with an average total error of 3–5%. The IKFS-2 measurements can be used for analyzing spatial and temporal (seasonal, interannual) variations in ozone, its long-term trends, verifying modern numerical stratospheric models, studying ozone anomalies, etc. The examples of analyzing TO in autumn-spring periods and TO anomalies in winter and spring of 2020 are given. They clearly demonstrate advantages of satellite TO measurements with the thermal radiation method.

臭氧层卫星监测

摘要

控制总臭氧 (TO) 和地表紫外线辐照度的重要性是使用各种地面和卫星方法和仪器持续监测臭氧层的原因。自 2015 年以来，俄罗斯仪器 IKFS-2 在 Meteor-M 2 号卫星上对 TO 进行了全球监测。这些测量是在全天和极夜条件下进行的。基于使用人工神经网络和 OMI 卫星仪器测量的开发算法会定期更新，并允许以 3-5% 的平均总误差确定 TO。IKFS-2 测量可用于分析臭氧的空间和时间（季节、年际）变化、其长期趋势、验证现代平流层数值模型、研究臭氧异常等。给出了2020年秋-春期TO和2020年冬春季TO异常的分析实例。它们清楚地展示了使用热辐射方法进行卫星 TO 测量的优势。
