Abstract :
This paper presents the characteristics of tropical rain profiles observed by the Precipitation Radar (PR) on TRMM satellite. Data for the entire year of 1998 were used in the analysis. The investigation focuses on the following questions: (1) given a surface rainfall rate, what are the typical rain profiles for different cloud and surface types? (2) Given the same surface rainfall rate, what is the variability of tropical rain profiles? How does it affect the microwave brightness temperatures? (3) How is the difference among rain profiles related to cloud development? The objectives of the study are both for better understanding the precipitation physics and for improving microwave remote sensing techniques
