Read the specification for a weighting type from a spec file.
[in,out]  file  Spec file. 
[out]  weighting_type  Aerosol weighting scheme. 
[out]  exponent  Exponent for powerlaw weighting (only used if weight_type is AERO_STATE_WEIGHT_POWER ). 
The weighting function is specified by the parameters:
flat
for flat weighting, flat_source
for flat weighting by source, power
for power weighting, power_source
for power source weighting, nummass
for number and mass weighting, and nummass_source
for number and mass weighting by source. If weight_type
is power
or power_source
then the next parameter must also be provided:power
or power_source
. Setting the exponent
to 0 is equivalent to no weighting, while setting the exponent negative uses more computational particles at larger diameters and setting the exponent positive uses more computaitonal partilces at smaller diameters; in practice exponents between 0 and 3 are most useful.See also:
