All GCMS:
More updates to enforce dynamics/physics separation:

get rid of references to "temps_mod" from physics packages;
make a "time_phylmdz_mod.F90" module to store that
information and fill it via "iniphysiq".

16c   subject:
17c   --------
18c   Subroutine designed to call the main canonic
19c   radiative transfer subroutine "lwmain" et "swmain"
20c   to compute radiative heating and cooling rate and
21c   radiative fluxes to the surface.
22c
23c   These calculations are only valid on the part of the atmosphere
24c   where Local Thermal Equilibrium (NLTE) is verified. In practice
25c   The calculations are only performed for the first "nlaylte"
26c   parameters (nlaylte is calculated by subroutine "nlthermeq"
27c   and stored in module "yomlw_h").
28c
29c   The purpose of this subroutine is to:
30c      1) Make some initial calculation at first call
31c      2) Split the calculation in several sub-grid
32c        ("sub-domain") to save memory and
33c        be able run on a workstation at high resolution
34c        The sub-grid size is defined in dimradmars_mod
35c      3) Compute the 3D scattering parameters depending on the
36c        size distribution of the different tracers (added by JBM)
37c      4) call "lwmain" and "swmain"

46c   ---------------------------------
47c
48c   This routine has been modified to take into account 3D, time
49c   dependent scattering properties of the aerosols.
50c---- The look-up tables that contain the scattering parameters
51c   of a given tracer, for different sizes, are read by SUAER.F90.
52c   The names of the corresponding ASCII files have to be set in
53c   this subroutine (file_id variable), and files must be in the
54c   directory specified in datafile.h. Please make sure that the
55c   ASCII files are correctly written, and that the range
56c   of particle sizes is consistent with what you would expect.
57c---- SUAER.F90 is in charge of reading the ASCII files and averaging
58c   the scattering parameters in each GCM channel, using the three last
59c   equations of Forget et al. 1998 (GRL 25, No.7, p.1105-1108).
60c---- These look-up tables, loaded during the firstcall, are then
61c   constantly used by the subroutine "aeroptproperties.F" to compute,
62c   online, the 3D scattering parameters, based on the size distribution
63c   (reffrad and nueffrad) of the different tracers, in each grid box.
64c   These 3D size distributions are loaded by the "updatereffrad.F"
65c   subroutine. A log-normal distribution is then assumed in
66c   "aeroptproperties.F", along with a Gauss-Legendre integration.
67c---- The optical depth at the visible reference wavelength (set in
68c   SUAER.F90, after the file_id variable) is then computed by
69c   the subroutine "aeropacity.F", by using the size and spatial
70c   distribution of the corresponding tracer. This connection has to
71c   be implemented in "aeropacity.F" when adding a new tracer. To do so,
72c   one can use equation 2 of Forget et al. 1998 (Icarus 131, p.302-316).
73c---- The resulting variables "aerosol", "QVISsQREF3d", "omegaVIS3d" and
74c   "gVIS3d" (same in the infrared) are finally used by lwmain.F and
75c   swmain.F to solve the radiative transfer equation.

77c   changes:
78c   -------
79c
80c   > SRL 7/2000
81c   
82c   This version has been modified to only calculate radiative tendencies
83c   over layers 1..NFLEV (set in dimradmars_mod).  Returns zero for higher
84c   layers, if any.
85c   In other routines, nlayer -> nflev.
86c   Routines affected: lwflux, lwi, lwmain, lwxb, lwxd, lwxn.
87c
88c   > J.-B. Madeleine 10W12
89c   This version uses the variable's splitting, which can be usefull
90c     when performing very high resolution simulation like LES.

93c   Here, solar band#1 is spectral interval between "long1vis" and "long2vis"
