Two previously report methods to invert the particle size distribution function PSDF from Mie scattering measurements on aerosol clouds are reconsidered and improvements are made in both. One of these methods - nonlinear regression - is described in greater detail than has previously been reported. Both techniques are tested by inverting the PSDF from noisy, synthetic scattering data. Some situations which result in ambiguities in determining the PSDF are identified and analyzed with the aid of residual error contour plots.
