Abstract

The results of microwave radiometry studies of the ozone-content dynamics in the middle atmosphere above Peterhof during stratospheric warmings of two winters, 2015–2016 and 2016–2017, are presented. Ground-based observations employed mobile microwave ozone-measuring instrument (operating frequency is 110.8 GHz). The vertical ozone distribution in the altitude range of 22–60 km is estimated. The results are compared to satellite-borne data on the total ozone content, to vertical profiles of the ozone and temperature in the middle atmosphere, and to data from an ozone-measuring sounder. In the middle atmosphere above Peterhof, there have been significant variations (by several times) in the ozone content at heights of 40–60 km due to minor stratospheric warming.

北极平流层突然变暖和亚极纬度期间中层大气臭氧含量大波动的检测

摘要

提出了在2015–2016年和2016–2017年两个冬季平流层变暖期间，彼得霍夫上方中层大气中臭氧含量动态的微波辐射测量研究结果。地面观测采用了移动式微波臭氧测量仪（工作频率为110.8 GHz）。估计海拔22–60 km内的垂直臭氧分布。将结果与有关臭氧总量的卫星传播数据，中层大气中臭氧的垂直分布和温度以及来自臭氧测量测深仪的数据进行比较。在彼得霍夫上方的中层大气中，由于平流层的轻微变暖，臭氧含量在40–60 km的高度上存在显着变化（数倍）。
