Observations of rain cells in the remains of a decaying tropical storm were made by Airborne Microwave Radiometers at 19.35, 92 and three frequencies near 183 GHz. Extremely loK^ brightnesa 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 obaervationa can ^.. interpreted in terms of the height of the ice. The brightness temperatutea observed wggeat the presence of precipitation sized ice as huh as 9 km or more.
