A preliminary report on Advanced Microwave Precipitation Radiometer measurements of tropical rainfall of cyclone Oliver

The Advanced Microwave Precipitation Radiometer (AMPR) was deployed during the Tropical Ocean Global Atmosphere (TOGA) Coupled Ocean-Atmospheric Response Experiment (COARE) from January 4 to February 24, 1993. The passive microwave signatures of a variety of precipitation features were sampled by the AMPR during this time. These data are used for convection and precipitation studies supporting the goals of NASA's Mission to Planet Earth. On February 8, 1993, the AMPR was flown over tropical cyclone Oliver which developed in the Western Pacific Ocean off the east coast of Townsville, Australia. The results of measurements indicated heavy rain within the eyewall of the cyclone as shown in the 10.7 GHz imagery, with precipitation size ice displaced down-shear (away from the eye) in the sloping eyewall.<>
