Abstract :
The strategy of TRMM Precipitation Radar (PR) calibration, including an external calibration scheme which employs active radar calibrators (ARCs) together with a special PR antenna scanning method, is discussed. This paper also covers data collection and processing schemes of the PR which were determined based upon scientific requirements and requirements of external calibration and onboard performance monitoring. Through the calibration, data collection and processing, the PR measurement is expected to provide a dataset which is valuable not only to obtain a reliable rainfall statistics but also detailed tropical storm properties
