Implementation in the LMDZ code of the double call of the ECRAD radiative transfer code to estimate the 3D radiative effect of clouds.

  • This double call of Ecrad is controlled by the ok_3Deffect logic key.
  • If this key is enabled, 2 files of parameter configuration "namelists" for ECRAD are required at runtime: namelist_ecrad and namelist_ecrad_s2.
  • If this key is deactivated, the configuration and initialization part (reading namelist and netcdf files) is performed only once during simulation (1st call to ECRAD). Otherwise, configuration and initialization are performed each time Ecrad is called.

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