用臭氧探空仪于1998年8月和10月测量了在拉萨上空的臭氧垂直分布,并与河北香河的观测资料进行了对比。结果表明,拉萨上空对流层臭氧浓度较低,在25～26 km之间臭氧分压最大,在30～34 km之间混合比最大。从典型的臭氧垂直分布廓线推算出大气臭氧总含量为261.6DU。

The ozone vertical distribution in the atmosphere over Lahsa was measured in August and October of 1998 with an ozone sonde, which also was compared with the result over Xianghe in Hebei province. The typical ozone profile showed that the ozone concentration in troposphere over Lahsa was lower, the maximum of ozone partial pressure appeared between 25～26 km and the maximum of ozone mixing ratio appeared between 30～34 km. The total ozone amount deduced from typical profile is 261.6 DU.
