Abstract : The general description of the 90 degrees scattering measurements of raindrop size distribution, as implemented in the AFCRL Airborne Raindrop Spectrometer, is given. The calibration procedures for the drop generator show long-time stability of the order of 01 mm drop diameter. The techniques for calibrating the spectrometer are described with the information required for data reduction. Calibration data for the simple current-to-voltage transducer and for a signal processor which removes the background illumination signal and stretches the drop pulse are presented. (Author)
