Summary:
Properties of a raindrop size distribution (DSD) parameter estimated from TRMM Precipitation Radar (PR) measurements are examined. The DSD parameter, called "ε" which is equivalent to the estimate of "a" in the radar reflectivity (Z) ? rail rate (R) relation, Z = aRb, shows a clear contrast between over land and over ocean. It also has a clear correlation with rain-top height and lightning activity derived from TRMM LIS measurement. Moreover, the seasonal variations of "a" over South India and Singapore show good correlations with ground-based disdrometer measurements. These results suggest that ε provides a means of global mapping of DSD.
