! rrtmg_sw aerosol optical properties
!
!  Data derived from six ECMWF aerosol types and defined for
!  the rrtmg_sw spectral intervals
!
! Initial: J.-J. Morcrette, ECMWF, mar2003
! Revised: MJIacono, AER, jul2006
!------------------------------------------------------------------
!
!-- The six ECMWF aerosol types are respectively:
!
!  1/ continental average                 2/ maritime
!  3/ desert                              4/ urban
!  5/ volcanic active                     6/ stratospheric background
!
! computed from Hess and Koepke (con, mar, des, urb)
!          from Bonnel et al.   (vol, str)
!
! rrtmg_sw 14 spectral intervals (microns):
!  3.846 -  3.077
!  3.077 -  2.500
!  2.500 -  2.150
!  2.150 -  1.942
!  1.942 -  1.626
!  1.626 -  1.299
!  1.299 -  1.242
!  1.242 -  0.7782
!  0.7782-  0.6250
!  0.6250-  0.4415
!  0.4415-  0.3448
!  0.3448-  0.2632
!  0.2632-  0.2000
