由从 TOMS 和基于地面的观察分析全部的臭氧数据,有极其低的臭氧的一个大区域在 12 月 14 日期间发生在西藏的高原上,这被发现 - 17, 2003。在在 TOMS 数据改正偏爱以后,有全部的臭氧 【 220DU 的区域被发现是超过 2500000 km~2,并且最小的值仅仅是 190 杜。是第一次一个臭氧微型洞或一个极其低的臭氧事件被发现发生在西藏的高原上。
By analyzing the total ozone data from TOMS and ground-based observations, it is found that a large area with extremely low ozone occurred over the Tibetan Plateau during December 14-17, 2003. After correcting the bias in TOMS data, the area with the total ozone 〈 220 DU is found to be over 2500000 km^2, and the minimum value is only 190 DU. It is the first time that an ozone mini-hole or an extremely low ozone event is found to occur over the Tibetan Plateau.
