readaerosol_optic_rrtm.F90 @ 2660

Last change on this file since 2660 was 2644, checked in by oboucher, 8 years ago
I introduced flag_bc_internal_mixture for BC/sulphate internal mixture. Only works for iflag_rrtm=y, NSW=6 and flag_aerosol=6 or aerosol_couple. It has no impact at the moment as LUT for aerosol properties will have to be changed. But the plumbing work is already done....
