Comparative Analysis of Cloud Base Heights Observed by Cloud Radar and Ceilometer
摘要
Abstract
From 1 May to 8 June 2013 CMA Meteorological Observation Centre conducted an experiment of cloud height observations by using cloud radar (35 GHz),whose observation data are the echo power value and temporal resolution is 1 min and a ceilometer whose observation data are the back-scattering intens da-ta with 1 min temporal resolution.The result of analyzing the data observed from the 39 d experiment indi-cates that:(1 )the data acquisition ratio of cloud radar is 2 6% larger than that of ceilometer;(2 )the ratio is 5 1% in fog-haze weather;(3 )relatively,precipitation has more significant effect on cloud base height measured by laser ceilometer than that by cloud radar;(4)height of cloud base measured by cloud radar is almost consistent with the height by ceilometer because their average deviation is less than 300 m.关键词
