摘要:

2009年6月20日~7月20日,中国海洋大学利用研制的可移式多普勒激光雷达系统在珠海市国家气候观象台(N22º 4’54”,E113º 12’50”)进行了为期一月的大气观测实验。报道了可移式多普勒激光雷达系统及观测实验,介绍了大气边界层高度检测原理及应用。利用一阶导数方法,对该系统实测数据进行了大气边界层高度检测和分析,讨论了有云存在时如何同时检测云高和大气边界层高度问题。实验结果表明,该区域和时间周期内的大气边界层高度范围在0.3~1.2km之间,平均高度为0.66km。

Abstract:

From June 20 to July 20, 2009, mobile Doppler wind lidar of Ocean University of China was operated in Zhuhai National Climate Observatory(N22o 4’54”,E113o 12’50”)for atmospheric observation. The lidar system, observation experiment, principle and application of atmospheric boundary layer height detection were introduced. In order to obtain the information of atmospheric boundary layer height, the measured data were processed and analyzed, using the first order derivative method. And the problem of how to detect atmospheric boundary layer height when existing clouds was also discussed. The results show that the height of atmospheric boundary layer is between 0.3km and 1.2km, and the average height is 0.66 km in Zhuhai from June to July of 2009.

Key words: atmospheric boundary layer height, inflexion point method, Lidar, cloud height
