Effect of Hail, Snow, and Melting Hydrometeors on Millimeter Radio Waves.
Abstract
This report is a short survey intended to present the effect of solid and melting hydrometeors on millimeter radio waves. Hail and sleet were found to be more amenable to theoretical calculation and laboratory experimentation than snow because of their simpler approximations of particle shape and dielectric constant. However, field measurements on hail and sleet are scarce in comparison to snow. The most pressing need was found to be the gathering of reliable field data on the morphology and size distribution of hydrometeor particles, particularly those in a melting state where the effect on millimeter waves may exceed that of rain. These data are needed to more closely relate experimental measurement to theoretical calculation. (Author)
