| Outline of Final Research Achievements |
We examined a method of identifying presence of supercooled liquid droplets using a 35 GHz band (Ka band) scanning-type cloud radar. In-situ observations using cloud particle sonde and cloud particle sensor (CPS) sonde and cloud radar observation were carried out. In cases that supercooled liquid droplets are present without ice particles, there is a possibility of identifying supercooled liquid droplets using radar reflectivity and differential reflectivity (ZDR). Since it is considered that the method is applicable in limited regions, other recent identification methods using radar without polarimetric function, lidar, and microwave radiometer were also summarized.
