| 摘 要： | 该文根据1998年6~10月上旬在拉萨地区进行的臭氧总量及臭氧垂直廓线的观测结果, 并结合同期同纬度其他两个臭氧站数据资料, 证实了以拉萨地区为代表的青藏高原在夏季存在“臭氧低谷”的现象.分析表明, 地基和卫星观测的臭氧总量有一定误差. Umkehr观测反演结果表明夏季拉萨地区平流层臭氧分布和同纬度其他地区相比略有不同; 在对流层, 探空资料显示了该地区对流层臭氧有低值分布的特征.

| Abstract: | An observational study on total ozone
amount and its vertical profile is presented using the measurements taken in Lhasa in the
summer of 1998. In combination with other data sets, it is proved that there is a natural
"ozone valley" over the Tibetan Plateau. Analyses show that there are errors on
total ozone amount between ground-based and satellite ozone measurements. Brewer Umkehr
observations demonstrate that the layer with maximum amount of ozone in the stratosphere
over Lhasa may exist in altitude ranging from 25 km to 27.5 km in summer, with higher
values and narrower width when compared with other regions in the same latitude. But the
Umkehr measurements overestimated the tropospheric ozone. Observations of ECC ozonesondes
show that there has obvious lower amount of ozone in the troposphere over Lhasa in the
summer season. |
