Workspace Method psdDelanoeEtAl14


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*.
