Rain type classification algorithm for TRMM precipitation radar

A TRMM precipitation radar (PR) standard algorithm for classifying precipitation types is designated as the algorithm 2A-23. This algorithm classifies precipitation type into three categories: stratiform, convective, and other. In the case of convective precipitation, a further examination is made to determine whether it is warm rain or not. The algorithm 2A-23 also detects bright band and determines the height of a bright band when it is detected.
