Abstract：Based on the cooperative measurement cloud technology of laser ceilometer and Ka-band cloud radar,this paper compares and analyzes the data of Liupanshan meteorological station in Ningxia from June 1 to July 31,2021.The cloud base height and cloud time data obtained by the two devices are compared in almost the same geographical location,and the influence of weather conditions on the observation performance of the two devices is further analyzed.The results show that under the same observation conditions,the observation results of the two devices are not the same.The reason is that the laser ceilometer is easily affected by some special weather phenomena,which are greatly affected by fog,haze,precipitation,etc.,leading to some deviations in cloud observation data.
