Online implementation of the radiative transfer code ECRAD in the LMDZ model.

  • Inclusion of the ecrad directory containing the sources of the ECRAD code
    • interface routine : radiation_scheme.F90
  • Adaptation of compilation scripts :
    • compilation under CPP key CPP_ECRAD
    • compilation with option "-rad ecard" or "-ecard true"
    • The "-rad old/rtm/ecran" build option will need to replace the "-rrtm true" and "-ecrad true" options in the future.
  • Runing LMDZ simulations with ecrad, you need :
    • logical key iflag_rrtm = 2 in physiq.def
    • namelist_ecrad (DefLists?)
    • the directory "data" containing the configuration files is temporarily placed in ../libfphylmd/ecrad/
  • Compilation and execution are tested in the 1D case. The repository under svn would allow to continue the implementation work: tests, verification of the results, ...

75!     The following factor is the ratio of total O2 band intensity (lines
76!     and Mate continuum) to O2 band intensity (line only).  It is needed
77!     to adjust the optical depths since the k's include only lines.
78Z_O2ADJ = 1.6_JPRB
79
80!     Compute the optical depth by interpolating in ln(pressure),
81!     temperature, and appropriate species.  Below LAYTROP, the water
82!     vapor self-continuum is interpolated (in temperature) separately.
