The effect of quantization on rainfall rate estimation from the Global Precipitation Measurement dual-frequency radar is studied quantitatively through numerical simulations. The error generated by a deterministic quantization or by a dithered quantization on rainfall rate estimation is combined with the errors from statistical fluctuation of the signal and the receiver noise. The preliminary results for the rain-rate range of 1-10 mmh-1 are presented.
