【Abstract】 The study of microwave radiometer applied in weather modification is presented. In general terms the first and most important prerequisite to“seedability”,is the existence of supercooled liquid water layer in clouds. Here we use a dual-channel radiometer to determine the integrated water vapor and the inte-grated liquid water separately. The frequencies employed 22. 235GHz and 35. 3GHz are close to an absorption line and in a window for water vapor respectively. A sta-tistical method for retrieving the total water vapor and cloud liquid water content are described. Some results of experiments in Hebei Province during spring to sum-mer of 1992 and 1993 are presented.更多还原
