ic_fu reff_def on/off
Specify wich definition of the effective radius is used.
If on the parameterization uses the original definition of the effective radius as specified in Fu1996,Fu1998.
Default is off. The same definition of the effective radius is used as the Key2002, Yang2000 and baum05a:_bulk,baum05b:_bulk parameterizations; see discussion of ic_properties.
ic_fu deltascaling on/off
Specify if the Fu1996 optical properties are delta-scaled or not.
If on delta-scaling is switched on.
If off delta-scaling is switched off. The default is without delta-scaling. Please note that this was changed on July 22, 2008: Before, delta-scaling was switched on by default which might have caused some confusion, because irradiance calculations were not consistent with the other ice cloud parameterizations implemented in uvspec. Using the Fu1996 parameterization in combination with one of ic_modify you now get consistent results with all other ice cloud parameterizations.
