在阿伯里斯特威斯（52.4°N，4.1°W）用扫描激光雷达系统测量卷云的后向散射和去偏振比。测量结果表明，最大发生高度接近9公里，约50%的云显示在某一高度存在具有近水平方向的冰晶。后向散射对垂直方向的角度依赖性表明，这些晶体与水平面的最大倾斜角约为0.3°。DOI：10.1034/j.1600-0889.1990.00001.x-i1
A scanning lidar system has been used at Aberystwyth (52.4°N, 4.1°W) to measure the backscatter and depolarization ratios in cirrus clouds. The measurements indicate that the height of maximum occurrence was near 9 km and that about 50% of clouds showed the presence at some height of ice crystals having a near horizontal orientation. The angular dependence of the backscatter about the vertical showed that the maximum tilt angle of these crystals from the horizontal plane was about 0.3°. DOI: 10.1034/j.1600-0889.1990.00001.x-i1
