Normalized PSD as proposed in Delanoë et al. ((2014)),

Title and journal: ‘Normalized particle size distribution for remote sensing application’, J. Geophys. Res. Atmos., 119, 4204–422.

The PSD has two independent parameters n0Star, the intercept parameter, and Dm, the volume-weighted diameter. This implementation expects as input two out of the following three quantities: iwc, n0Star, Dm. In this case one of the input parameters iwc, n0Star, Dm must be set to -999. It is also possible to provide only iwc, in which case an a priori assumption will be used to deduce n0Star from temperature. In this case both n0Star and Dm must be set to -999.0.

This PSD is not defined for vanishing concentrations of scatterers as it requires normalization by Dm. It is up to the user to ensure that the value of Dm is sufficiently large. An error is thrown if Dm is zero or below the value provided by dm_min.
