Millimeter-wavelength radars bridge an observational gap
in Earth's hydrological cycle by adequately detecting clouds
and precipitation, thus offering a unique and more holistic
view of the water cycle in action.

he choice of operating wavelength for
a radar (from radio detection and rang-
ing) is framed by two physical realities.
For radars with the same resolution volume
and transmitted power, as the operating
wavelength gets shorter the radar is capable of
detecting smaller particles (Lhermitte 1987);
