Abstract :
The author tried to get data indicating a phase change from cloud droplets to snow particles without aircraft observations. The author used the data obtained from a radar for measuring snow and from a microwave radiometer for measuring column liquid water contents. A case study of the WISP91 was analyzed. The data shows that the radar reflectivity in the layer below 1 km height became strong at the time, when the column liquid contents suddenly dropped to about 0.1 mm from 0.4 mm. This fact suggests the phase change from cloud droplets to snow particles occurred for a short period
