In this paper, we propose a simple and fast technique to retrieve total ozone from measurements of spectral top-of-atmosphere reflectance for cloudless atmosphere over Antarctica. It is assumed that both snow and atmosphere are clean and not influenced by pollution. Spaceborne measurements performed by Ocean Land and Colour Instrument (OLCI) onboard the Sentinel-3 mission over Dome C (Antarctica) are analysed. The results of the retrievals are compared with those performed by the Ozone Monitoring Instrument (OMI) on board the Aura satellite. Good correspondence of the derived total ozone columns is found. This work opens a door for fast ozone retrievals using high spatial resolution imagery with frequent re-visit time over polar areas covered by snow and ice.

在本文中，我们提出了一种简单而又快速的技术，该技术可以通过对南极上空无云大气的光谱最高大气反射率进行测量来检索总臭氧。假定雪和大气都清洁且不受污染影响。分析了由海洋陆地和彩色仪器（OLCI）进行的对圆顶C（南极洲）进行的Sentinel-3任务进行的星空测量。将检索结果与Aura卫星上的臭氧监测仪（OMI）进行的结果进行比较。发现派生的总臭氧柱良好对应。这项工作为利用高空间分辨率图像以及在冰雪覆盖的极地区域频繁重新访问时间快速恢复臭氧打开了一扇门。
