摘要
利用1985—2002年SAGEⅡ卫星资料获取青藏高原地区上空大气臭氧垂直廓线,分析其变化规律。结果表明:①卫星资料与地面臭氧探空资料有很好的一致性;②青藏高原上空大气臭氧垂直廓线存在南北间的差异和季节变化,夏秋季臭氧廓线极大值出现的位置比冬春季高出1～2km(高原南部)和2～3km(高原北部);③臭氧数浓度在10～20km的高度存在明显季节和南北区域差异;④与同纬度其他地区的平均值相比,夏季(6—9月)臭氧低值主要出现在15～20km的高原对流层顶附近,最低值出现在18km附近,而冬季这种差异相对较小。
The vertical ozone profiles over Tibetan Plateau were obtained from SGAE Ⅱ satellite data during 1985--2002 for the analysis of their change rule. The results were as follows： ①The satellite data showed good consistency with the ground-base ozone air-sounding data. ②There existed seasonal changes and spatial （from north to south） variations of the vertical ozone over the plateau, and the position with maximum vertical ozone profile in summer and autumn seasons was 1 ～ 2 km （south part of the plateau） or 2 ～3 km （north part of the plateau） higher than that in winter and spring seasons. ③There existed distinct seasonal and spatial differences of ozone concentration in the altitudes between 10 and 20 km. ④Ozone deficits in the summer were found in the altitudes between 15 and 20 km （maximum in 18 km） when comparing the vertical ozone over the plateau with those over the non-plateau area with the same latitude, whereas they showed little difference in winter
