To estimate raindrop size distributions aloft, we fit a theoretical Doppler spectrum of a model drop size distribution to observed Doppler power spectra measured by a 915 MHz profiler, while using concurrent information supplied by a 50 MHz profiler to correct for vertical winds. While several assumptions have been made in deriving the theoretical Doppler spectrum, model derived rainfall rates compare favorably with locally measured rainfall rates obtained from rain gauge estimates.
