摘要

对GTS1型探空仪资料分析云高和CL51激光云高仪所测云高进行对比,分析两者的云高差异。结果表明,2种探测系统在中云的判断上,所测云高吻合度最高,具有较好的相关性;对低云、高云的云高判断存在差距。要提高这2种探测系统对云高的测量准确度,需要在地面高湿情况下,对阈值法和温度露点法的应用进行优化;在雾霾和大雨天气下,对激光云高仪测云性能加以提高;在低温下对探空仪湿度传感器的性能加以改进。
        The cloud heights measured by GTS1 radiosonde and CL51 laser ceilometer were compared, and the difference of cloud heights between them was analyzed. The results showed that the two detection systems had the highest coincidence and good correlation in the judgment of middle cloud, but there was a gap in the judgment of low cloud and high cloud. In order to improve the accuracy of cloud height measurement by these two detection systems, it was necessary to optimize the application of threshold method and temperature dew point method under high humidity conditions on the ground, to improve the performance of cloud height measurement by laser cloud altimeter in fog and heavy rain, and to improve the performance of humidity sensor of sounder at low temperature.
