Comparison of different cloud height observation equipment Cloud Radar laser ceilometer Lidar-MPL Sounding In the test base, Carry out comparative tests on data acquisition rate, accuracy and cloud base height recognition ability of cloud radar, lidar-MPL, laser ceilometer, radio sonde, so as to improve the cloud base height recognition ability. under different cloud types and different weather conditions. Preliminary conclusion: The cloud base of the cloud radar is lower by -0.5%, and the laser 19 ceilometer is higher by 5% ， compared with cloud base height of the sounding.
