摘要

摘要: 运用激光雷达方程和Fernald方法，对西藏那曲地区和北京地区对流层气溶胶的微脉冲激光雷达(MPL)探测数据进行时空反演和比较，结果表明：气溶胶散射比廓线有着较为相似的结构分布，分层锯齿结构非常明显，主要包括贴地层、气溶胶混合层和气溶胶对流层。那曲测站上空气溶胶散射比在无云条件下最大值基本上保持在2.0左右；在测站上空均存在密度较大且较厚的积云；夏季的混合层或残留层(浅蓝色部分)高度抬高；夏季对流层低层积云的云量和积云出现的概率较冬季要少。

Abstract: Qinghai-Tibet plateau is famous for the name of the third pole of the earth. The aerosol vertical scattering ratio profiles and extinction coefficient time-space distribution at Naqu prefecture and Beijing prefecture were shown and compared. The data shows that: the similar multi-layered zigzag vertical structure of aerosol extinction coefficient distribution exists in the day and night time; the layers include close ground layer, mixed layer and troposphere. The maximum value of aerosol scattering ratio remains at 2.0 under cloud-free conditions. Because of the vapor cycle, cumulus is existed over the prefecture most of the time, and presence probability of cumulus in summer is less than in winter.
