【摘要】 工作波长为532 nm的机载大气环境探测激光雷达AEDAR(Atmospheric Environment Detecting Airborne Lidar) 装载在CMS-3807飞机上,于2005年11月7日至11日期间在青岛地区及周边海域上空进行了飞行探测．此次实验的目的有两个:验证我国用于大气环境探测的激光雷达技术已经具备从地基向空基乃至天基发展的条件;获得青岛地区及周边海域边界层结构及大气气溶胶时空分布变化的特点．激光雷达的高时空分辨率为获取飞行路径上的边界层结构及气溶胶时空分布提供了可能．为了研究下垫面对边界层及气溶胶时空分布的影响,预定的飞行路径上包含了丰富的地形变化,有城市、丘陵、海陆交界区及海区等．通过给出11月8日及11日的探测结果,不仅得到了不同地区边界层结构及气溶胶的时空分布特点,还可以看到地形,地面气象场等因素对它们的影响．更多还原

【Abstract】 The AEDAL ( Atmospheric Environment Detecting Airborne Lidar) operating at the 532 nm Nd.YAG wavelength was flown aboard the China Marine Service (CMS) 3807 over the Qingdao area. The primary aims of this platform were to prove the capability to develop airborne lidar available in our country, meanwhile, get the spatial and temporal variations of the atmosphere boundary layer (ABL) and aerosol distribution along flight lines. In order to investigate the effect of topography on the ABL and aerosol distribution, various terrains were included under the predetermined flight lines. The comparison of the AEDAL results on the days of 8 and 11 November, 2005, showed the spatial and temporal variations of the ABL and aerosol distribution are impacted by meteorological factors such as temperature, humidity, pressure, wind, and even terrain feature.更多还原
