!======================================================================

!     RADIATION parameters

!     In radiation code, layer 1 corresponds to the stratosphere.  Level
!     1 is the top of the stratosphere.  The dummy layer is at the same
!     temperature as the (vertically isothermal) stratosphere, and
!     any time it is explicitly needed, the appropriate quantities will
!     be dealt with (aka "top". . .)

!     L_NLEVRAD corresponds to the surface - i.e., the GCM Level that
!     is at the surface.  PLEV(L_NLEVRAD) = P(J,I)+PTROP, 
!     PLEV(2) = PTROP, PLEV(1) = ptop

!     L_NLAYRAD is the number of radiation code layers
!     L_NLEVRAD is the number of radiation code levels.  Level N is the
!               top of layer N. 
!
!     L_NSPECTI is the number of IR spectral intervals
!     L_NSPECTV is the number of Visual(or Solar) spectral intervals
!     L_NGAUSS  is the number of Gauss points for K-coefficients
!               GAUSS POINT 17 (aka the last one) is the special case
!
!     L_NPREF   is the number of reference pressures that the 
!               k-coefficients are calculated on
!     L_PINT    is the number of Lagrange interpolated reference
!               pressures for the gas k-coefficients - now for a
!               smaller p-grid than before
!     L_NTREF   is the number of reference temperatures for the
!               k-coefficients
!     L_TAUMAX  is the largest optical depth - larger ones are set
!               to this value
!
!     L_REFVAR  The number of different mixing ratio values for
!               the k-coefficients. Variable component of the mixture
!               can in princple be anything: currently it's H2O.
!
!     NAERKIND  The number of radiatively active aerosol types
!
!     NSIZEMAX  The maximum number of aerosol particle sizes

! Maximum number of grain size classes
! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
!   This parameter has to be set to the maximum number of particle
!   sizes contained in the optical parameter database; For example,
!   if only one grain size is used to describe dust, and 30 are used
!   to describe water-ice crystals in the visible and 15 in the IR,
!   nsizemax has to be set to 30.
!   If only one grain size is considered for all the aerosols, set
!   this parameter to 1 and convolution will be turned off during
!   the radiative calculations.
