To understand the microphysical structure of weather systems that lead to severe precipitation, this project proposes a research study for observation and data analysis of Vertical Pointing Microwave Rain Radar(VPRR). The vertical structure of precipitation system in troposphere will be obatined by way of observations of VPRR during Mei-Yu and typhoon season, and the technique of radar quantitative precipitation estimate can be improved. The program include:(1)applying the data observed by VPRR and ground disdrometer to analyze the vertical structure of precipitation systems,(2)to frame the observation strategy of VPRR, and (3) to establish the standard operating procedure of data collecting, processing, quality controlling, and analyses.微波降雨雷達
