Abstract:
From January to May 2015 CMA Meteorological Observation Centre conducted an experiment of cloud observation by one Kaband solidstate millimeter wave ceilometer (HT101) and two kinds of laser ceilometers (CYY2B and HYCL51). During the experiment taking the heights of Lband sounding balloons passing through the cloud base as the standards of the cloud base height, the whole sky infrared cloud measuring system and the automatic meteorological station as auxiliary equipment, the different types of ceilometers are analyzed in the aspects of completeness, accuracy, data acquisition rate, and weather adaptability. The results show that the detection capability of HT101 is better than CYY2B and HYCL51 Main results are as follows: (1) The data acquisition rate of HT101 is the highest. (2) HT101 has the higher detection accuracy of cloud base heights than CYY2B and HYCL51 (3) HT101 has the stronger capability to detect cloud top heights. (4) HT101 has the better weather adaptability than CYY2B and HYCL51
