56! PURPOSE
57! -------
58!   The modular radiation scheme is contained in a separate
59!   library. This routine puts the the IFS arrays into appropriate
60!   objects, computing the additional data that is required, and sends
61!   it to the radiation scheme.  It returns net fluxes and surface
62!   flux components needed by the rest of the model.
63!
64!   Lower case is used for variables and types taken from the
65!   radiation library
66!
67! INTERFACE
68! ---------
69!    RADIATION_SCHEME is called from RADLSWR. The
70!    SETUP_RADIATION_SCHEME routine (in the RADIATION_SETUP module)
71!    should have been run first.
