Precipitation Analysis of Passive Microwave Data from the Advanced Microwave Precipitation Radiometer during the Tropical Cloud Systems and Processes Experiment

The Advanced Microwave Precipitation Radiometer (AMPR) is a passive microwave scanning radiometer which flew on the NASA ER-2 during the field-phase of the Tropical Cloud Systems and Processes (TCSP) experiment conducted in July 2005. TCSP is a collaboration between NASA, NOAA-HRD, universities, and the Costa Rican Weather Service to study tropical cyclogenesis and intensification. AMPR produces calibrated brightness temperatures at 10.7, 19.35, 37.1, and 85.5 GHz, ideal for studying precipitation. An overview of missions with emphasis on the analysis of horizontal distribution and intensity of precipitation in category four Hurricane Emily on July 17th, development and landfall of Tropical Storm Gert on July 24th and 25th, and the development and intensification of Dennis from a tropical storm on July 5th to a category three hurricane by July 9th will be presented.
