! Fortran-95 implementation of the Mersenne Twister 19937, following 
!   the C implementation described below (code mt19937ar-cok.c, dated 2002/2/10), 
!   adapted cosmetically by making the names more general.  
! Users must declare one or more variables of type randomNumberSequence in the calling 
!   procedure which are then initialized using a required seed. If the 
!   variable is not initialized the random numbers will all be 0. 
! For example: 
! program testRandoms 
!   use RandomNumbers
!   type(randomNumberSequence) :: randomNumbers
!   integer                    :: i
!   
!   randomNumbers = new_RandomNumberSequence(seed = 100)
!   do i = 1, 10
!     print ('(f12.10, 2x)'), getRandomReal(randomNumbers)
!   end do
! end program testRandoms

! Purpose: Create McICA stochastic arrays for cloud physical or optical properties.
! Two options are possible:
! 1) Input cloud physical properties: cloud fraction, ice and liquid water
!    paths, ice fraction, and particle sizes.  Output will be stochastic
!    arrays of these variables.  (inflag = 1)
! 2) Input cloud optical properties directly: cloud optical depth, single
!    scattering albedo and asymmetry parameter.  Output will be stochastic
!    arrays of these variables.  (inflag = 0; longwave scattering is not
!    yet available, ssac and asmc are for future expansion)

  ! Original code: Based on Raisanen et al., QJRMS, 2004.
  ! 
  ! Modifications: Generalized for use with RRTMG and added Mersenne Twister as the default
  !   random number generator, which can be changed to the optional kissvec random number generator
  !   with flag 'irng'. Some extra functionality has been commented or removed.  
  !   Michael J. Iacono, AER, Inc., February 2007
  !
  ! Given a profile of cloud fraction, cloud water and cloud ice, we produce a set of subcolumns.
  ! Each layer within each subcolumn is homogeneous, with cloud fraction equal to zero or one 
  ! and uniform cloud liquid and cloud ice concentration.
  ! The ensemble as a whole reproduces the probability function of cloud liquid and ice within each layer 
  ! and obeys an overlap assumption in the vertical.   
  ! 
  ! Overlap assumption:
  !  The cloud are consistent with 4 overlap assumptions: random, maximum, maximum-random and exponential. 
  !  The default option is maximum-random (option 3)
  !  The options are: 1=random overlap, 2=max/random, 3=maximum overlap, 4=exponential overlap
  !  This is set with the variable "overlap" 
  !mji - Exponential overlap option (overlap=4) has been deactivated in this version
  !  The exponential overlap uses also a length scale, Zo. (real,    parameter  :: Zo = 2500. ) 
  ! 
  ! Seed:
  !  If the stochastic cloud generator is called several times during the same timestep, 
  !  one should change the seed between the call to insure that the subcolumns are different.
  !  This is done by changing the argument 'changeSeed'
  !  For example, if one wants to create a set of columns for the shortwave and another set for the longwave ,
  !  use 'changeSeed = 1' for the first call and'changeSeed = 2' for the second call 
  !
  ! PDF assumption:
  !  We can use arbitrary complicated PDFS. 
  !  In the present version, we produce homogeneuous clouds (the simplest case).  
  !  Future developments include using the PDF scheme of Ben Johnson. 
  !
  ! History file:
  !  Option to add diagnostics variables in the history file. (using FINCL in the namelist)
  !  nsubcol = number of subcolumns
  !  overlap = overlap type (1-3)
  !  Zo = length scale 
  !  CLOUD_S = mean of the subcolumn cloud fraction ('_S" means Stochastic)
  !  CLDLIQ_S = mean of the subcolumn cloud water
  !  CLDICE_S = mean of the subcolumn cloud ice 
  !
  ! Note:
  !   Here: we force that the cloud condensate to be consistent with the cloud fraction 
  !   i.e we only have cloud condensate when the cell is cloudy. 
  !   In CAM: The cloud condensate and the cloud fraction are obtained from 2 different equations 
  !   and the 2 quantities can be inconsistent (i.e. CAM can produce cloud fraction 
  !   without cloud condensate or the opposite).

!  This program calculates the upward fluxes, downward fluxes, and
!  heating rates for an arbitrary clear or cloudy atmosphere.  The input
!  to this program is the atmospheric profile, all Planck function
!  information, and the cloud fraction by layer.  A variable diffusivity 
!  angle (SECDIFF) is used for the angle integration.  Bands 2-3 and 5-9 
!  use a value for SECDIFF that varies from 1.50 to 1.80 as a function of 
!  the column water vapor, and other bands use a value of 1.66.  The Gaussian 
!  weight appropriate to this angle (WTDIFF=0.5) is applied here.  Note that 
!  use of the emissivity angle for the flux integration can cause errors of 
!  1 to 4 W/m2 within cloudy layers.  
!  Clouds are treated with the McICA stochastic approach and maximum-random
!  cloud overlap.

!  The subroutines CMBGB1->CMBGB16 input the absorption coefficient
!  data for each band, which are defined for 16 g-points and 16 spectral
!  bands. The data are combined with appropriate weighting following the
!  g-point mapping arrays specified in RRTMINIT.  Plank fraction data
!  in arrays FRACREFA and FRACREFB are combined without weighting.  All
!  g-point reduced data are put into new arrays for use in RRTM.

! -------- Description --------

! This program is the driver subroutine for RRTMG_LW, the AER LW radiation 
! model for application to GCMs, that has been adapted from RRTM_LW for
! improved efficiency.
!
! NOTE: The call to RRTMG_LW_INI should be moved to the GCM initialization
!  area, since this has to be called only once. 
!
! This routine:
!    a) calls INATM to read in the atmospheric profile from GCM;
!       all layering in RRTMG is ordered from surface to toa. 
!    b) calls CLDPRMC to set cloud optical depth for McICA based 
!       on input cloud properties 
!    c) calls SETCOEF to calculate various quantities needed for 
!       the radiative transfer algorithm
!    d) calls TAUMOL to calculate gaseous optical depths for each 
!       of the 16 spectral bands
!    e) calls RTRNMC (for both clear and cloudy profiles) to perform the
!       radiative transfer calculation using McICA, the Monte-Carlo 
!       Independent Column Approximation, to represent sub-grid scale 
!       cloud variability
!    f) passes the necessary fluxes and cooling rates back to GCM
!
! Two modes of operation are possible:
!     The mode is chosen by using either rrtmg_lw.nomcica.f90 (to not use
!     McICA) or rrtmg_lw.f90 (to use McICA) to interface with a GCM. 
!
!    1) Standard, single forward model calculation (imca = 0)
!    2) Monte Carlo Independent Column Approximation (McICA, Pincus et al., 
!       JC, 2003) method is applied to the forward model calculation (imca = 1)
!
! This call to RRTMG_LW must be preceeded by a call to the module
!     mcica_subcol_gen_lw.f90 to run the McICA sub-column cloud generator,
!     which will provide the cloud physical or cloud optical properties
!     on the RRTMG quadrature point (ngpt) dimension.
!     Two random number generators are available for use when imca = 1.
!     This is chosen by setting flag irnd on input to mcica_subcol_gen_lw.
!     1) KISSVEC (irnd = 0)
!     2) Mersenne-Twister (irnd = 1)
!
! Two methods of cloud property input are possible:
!     Cloud properties can be input in one of two ways (controlled by input 
!     flags inflglw, iceflglw, and liqflglw; see text file rrtmg_lw_instructions
!     and subroutine rrtmg_lw_cldprop.f90 for further details):
!
!    1) Input cloud fraction and cloud optical depth directly (inflglw = 0)
!    2) Input cloud fraction and cloud physical properties (inflglw = 1 or 2);  
!       cloud optical properties are calculated by cldprop or cldprmc based
!       on input settings of iceflglw and liqflglw.  Ice particle size provided
!       must be appropriately defined for the ice parameterization selected. 
!
! One method of aerosol property input is possible:
!     Aerosol properties can be input in only one way (controlled by input 
!     flag iaer; see text file rrtmg_lw_instructions for further details):

!    1) Input aerosol optical depth directly by layer and spectral band (iaer=10);
!       band average optical depth at the mid-point of each spectral band.
!       RRTMG_LW currently treats only aerosol absorption;
!       scattering capability is not presently available.

!     index in the array, JT, which runs from 1 to 5, corresponds to 
!     different temperatures.  More specifically, JT = 3 means that the 
!     data are for the corresponding TREF for this  pressure level, 
!     JT = 2 refers to the temperatureTREF-15, JT = 1 is for TREF-30, 
!     JT = 4 is for TREF+15, and JT = 5 is for TREF+30.  The second 
!     index, JP, runs from 1 to 13 and refers to the corresponding 
!     pressure level in PREF (e.g. JP = 1 is for a pressure of 1053.63 mb).  
!     The third index, IG, goes from 1 to 16, and tells us which

!     The array KAO contains absorption coefs for each of the 16 g-intervals
!     for a range of pressure levels > ~100mb, temperatures, and ratios
!     of water vapor to CO2.  The first index in the array, JS, runs

!     as expressed through the binary species parameter eta, defined as
!     eta = gas1/(gas1 + (rat) * gas2), where rat is the 
!     ratio of the reference MLS column amount value of gas 1 
!     to that of gas2.
!     The 2nd index in the array, JT, which runs from 1 to 5, corresponds 
!     to different temperatures.  More specifically, JT = 3 means that the 
!     data are for the reference temperature TREF for this  pressure

!     TREF-15, JT = 1 is for TREF-30, JT = 4 is for TREF+15, and JT = 5

!     pressure of 1053.63 mb).  The fourth index, IG, goes from 1 to 16,
!     and tells us which g-interval the absorption coefficients are for.

!     The array KA_Mxx contains the absorption coefficient for 
!     a minor species at the 16 chosen g-values for a reference pressure

!     eta = gas1/(gas1 + (rat) * gas2), where rat is the 
!     ratio of the reference MLS column amount value of gas 1 
!     to that of gas2.  The second index refers to temperature 
!     in 7.2 degree increments.  For instance, JT = 1 refers to a 
!     temperature of 188.0, JT = 2 refers to 195.2, etc. The third index 
!     runs over the g-channel (1 to 16).

!     The array FORREFO contains the coefficient of the water vapor
!     foreign-continuum (including the energy term).  The first

!     The array SELFREFO contains the coefficient of the water vapor
!     self-continuum (including the energy term).  The first index
!     refers to temperature in 7.2 degree increments.  For instance,
