Abstract : The results of a study of the measurement of rainfall by radar at a range of 75 miles are presented. Some of the problems of radar measurements at this range are found to be attenuation and effects of the radar beam's vertical extent at distant ranges. The analysis of drop-size data from rains at Flagstaff, Arizona shows that the radar-rainfall relationships there are quite different from those measured elsewhere by the drop camera technique. Results of a study of drop-size distributions from New Jersey and North Carolina are presented. In many respects, the data from these two locations are similar. A paper dealing with the analysis of drop-size data from Florida and Oregon is included as an appendix. (Author)
