50! PURPOSE
51! -------
52!   The modular radiation scheme is contained in a separate
53!   library. This routine puts the the IFS arrays into appropriate
54!   objects, computing the additional data that is required, and sends
55!   it to the radiation scheme.  It returns net fluxes and surface
56!   flux components needed by the rest of the model.
57!
58!   Lower case is used for variables and types taken from the
59!   radiation library
60!
61! INTERFACE
62! ---------
63!    RADIATION_SCHEME is called from RADLSWR. The
64!    SETUP_RADIATION_SCHEME routine (in the RADIATION_SETUP module)
65!    should have been run first.
