A study of influence on stratospheric composition in mid-latituderegion by Antarctic ozone hole based on ground-based millimeter-wave measurements

我们在南极洲附近的阿根廷里奥加列戈斯新安装了一台毫米波辐射计，并开始连续测量臭氧在平流层中的垂直分布，以评估臭氧空洞内气团输送造成的中纬度地区的臭氧消耗。从辐射计每隔5分钟观测到的光谱中提取了臭氧的垂直廓线，并通过与臭氧激光雷达和其他仪器的测量结果进行了比较，验证了该方法的有效性。

We newly installed a millimeter-wave radiometer at Rio Gallegos, Argentina, located near the Antarctica, and started continuous measurements of the vertical distribution of ozone in the stratosphere for evaluating ozone depletion in the mid-latitude region caused by transport of the airmass inside the ozone hole. The vertical profile of ozone has been retrieved from the spectrum observed with the radiometer every 5 minutes, and has been validated by comparisons among the measurements with an ozone LIDAR and other instruments.
