Another possible candidate explanation is that the DSD, and the associated Z-R relations, systematically change from the altitude where R can be realistically measured with a radar, and the surface where the gages are located. Work on the resolution of this discrepancy is continuing. The Miami data goes back to Ja nuary 1996, Key West to June 1997, and the Melbourne and Tampa data to March 1998. AS part of the updated website are examples of rainfall distributions diurnally, in cold frontal passages, and tropical cyclones. Evidence from tropical raindrop spectra of the origin of rain from stratiform versus convective clouds.
