Ice crystal habit for the Yang2000, Key2002 and
hey parameterizations, see also ic_properties key/yang/hey.
ic_habit type
For Key/Yang type may be one of solid-column,
hollow-column, rough-aggregate, rosette-4,
rosette-6, plate, droxtal, dendrite
and spheroid. Please note that this parameterization is only valid for
a restricted size range, depending on the habit (see table 1 in
Key2002. Also, some of the habits are only available for
wavelengths below 5 micrometer (rosette-4) while others are only available
for wavelengths larger than 3 micrometer (droxtal, spheroid).
For hey the following habits can be chosen: solid-column, hollow-column, rough-aggregate, rosette-6, plate, and droxtal; here all habits are available for effective radii from 5 to 90 micrometers in the wavelength region from 0.2 to 5 micrometers.
