1. A system for measuring metrics of a backscattering population of water particles of a cloud atmosphere, the system comprising:

  • a quasi-optical transmitter configured to project a pulse of quasi-optical energy from a horn aperture into a divergent projection volume of the cloud atmosphere, the divergent projection volume defined by an axis of projection and an angle of projection about the axis of projection, the angle of projection based on a ratio of a transverse dimension of the horn aperture to a wavelength of the quasi-optical energy;

    a quasi-optical receiver configured to detect a portion of the projected pulse of quasi-optical energy backscattered by the backscattering population of water particles within the divergent projection volume of the cloud atmosphere; and

    a cloud metric calculator configured to determine, based on a detected portion of the projected pulse of quasi-optical energy backscattered by the backscattering population of water particles within the divergent projection volume of the cloud atmosphere, a density of the backscattering population of water particles within the divergent projection volume of the cloud atmosphere.
