!-- The six aerosol types are respectively:

!  1/ continental average                 2/ maritime
!  3/ desert                              4/ urban
!  5/ volcanic active                     6/ stratospheric background

! The quantities given are:
! TAU : ratio of average optical thickness in interval to that at 0.55 
!       micron
! PIZA: average single scattering albedo
! CGA : average asymmetry factor

! computed from Hess and Koepke (con, mar, des, urb)
!          from Bonnel et al.   (vol, str)

!-- data are entered for the 6 spectral intervals of the LW scheme (line)
!   and the different types of aerosols (column)
