This paper summarizes some of the highlights of the symposium, synthesizes them in the context of prior observations and understanding, and attempts to resolve apparent conflicts. The differential reflectivity ZDR technique has shown excellent results in the quantitative measurement of rainfall. Systematic differences were found to be due to deviations from the originally assumed exponential drop size distribution. The consensus was that the circular depolarization ratio (CDR) method is more versatile and powerful but that ZDR is simpler and cheaper. Precautions in the use of ZDR have been noted. The apparent conflict between CDR and ZDR measurements near the melting layer seems to have been resolved. A spectrum of scientific and practical applications has been identified. Most importantly, the ZDR method is recommended for further development and use wherever accurate rainfall measurements are required.
