Comparison of different fittings of experimental DSD

Retrieval of a distribution of raindrop sizes from measured drop spectra is critically influenced by the tail of the distribution. The influence of various tail-types is studied with reference to four parameterisations fitted both to the large dropsonlyand to the entire sample of the disdrometer-measured spectra. Results of this preliminary analysis show that the Weibull distribution with a shape parameter greater than oneseems to fit the highest percentages of the measured drop spectra.
