Unusual changes in the Antarctic Middle Atmosphere during the 2019 Warming in the Southern Hemisphere

For the Antarctic mesosphere study, we used wind measurements by the King Sejong Station (62.22^oS, 58.78°W) Meteor Radar (KSSMR). The KSS MR provides winds from the altitude 70 km to 100 km with 1 hour and 2 km height resolutions. Here we uploaded the daily zonal and meridional winds during July to October of Southern Hemisphere. The data files contains the height and time evolution of wind components. Each file contains the height (First Column) and Winds (from Second column). The time period is from Julian Day 180 to 285 for the year 2019.本研究针对南极中层大气，采用位于62.22°S、58.78°W的世宗王站气象雷达（King Sejong Station Meteor Radar，缩写KSSMR）获取的风场测量数据。该雷达可提供70 km至100 km高度区间的风场数据，时间分辨率为1小时，高度分辨率为2 km。本次上传了南半球7月至10月的逐日纬向风与经向风数据。数据文件包含风分量的高度与时间演变特征。每个文件的第一列为高度数据，第二列及后续列为风场数据。本数据集的时间范围为2019年儒略日180至285。
