Meteorologists, both operational and forensic, often use hydrometeor classification algorithms (techno-speak for algorithms that offer a best-guess as to the type of precipitation occupying a given section of sky) as a first step in identifying likely regions of hail production, although we take the algorithm output with a healthy grain (or two) of salt when conditions warrant.

The first moment about zero, mean Doppler shift, [8] is related to the radial motion of particles in the sample volume, and the first moment about the spectrum mean, Doppler frequency dispersion, is a measure of hydrometeor radial velocity dispersion.
Four state-of-the-art scanning dualpolarization Doppler radars, operating at several frequencies, observed the vertical and horizontal variability of hydrometeor characteristics and air motions within passing storms.
Writing for scientists, practicing engineers, or designers concerned with the operation and service of radio links, Blaunstein and Christodoulou examine different situations in the over-the-terrain, atmospheric, and ionospheric communication channels, including rural, mixed residential, and built-up environments for terrestrial links, atmospheric turbulence, and different kinds of hydrometeors.
His topics are radio waves and the troposphere, propagation, reflection and interference, refraction and path delay, absorption, rain attenuation, and attenuation by hydrometeors other than rain.

The free space losses, the excess losses due to the atmospheric gases, oxygen molecules, salt, and hydrometeors (rain, snowflakes, fog, and clouds, etc) consist make the losses of the propagating electromagnetic wave ("excess" in this context means in excess of free--space loss) [1].
Following a historical overview of radiative transfer and microwave radiometry, the book covers atmospheric, terrestrial, and technical factors affecting the use of thermal microwave radiation in remote sensing applications, with chapters on the absorption and emission spectra of atmospheric gases, the interaction of solid and liquid hydrometeors with microwave radiation, radiative-transfer modeling of the microwave surface emission, and dielectric properties of important materials found at the terrestrial surface.
