Microwave radiometric observations near 19.35, 92 and 183 GHz of precipitation in tropical storm Cora.

Abstract

Extremely low brightness temperatures, as low as 140 K, were noted in the 92 and 183 GHz observations. These can be accounted for by the ice often associated with raindrop formation. Further, the 183 GHz observations can be interpreted in terms of the height of the ice. The brightness temperatures observed suggest the presence of precipitation-sized ice as high as 9 km or more.-from Authors
