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, ...

11! *** This program is the driver for the McICA version of RRTM_LW,
12!     the AER rapid model.

14!     For each atmosphere the user wishes to analyze, this routine
15!     a) calls ECRTATM to read in the atmospheric profile
16!     b) calls SETCOEF to calculate various quantities needed for
17!        the radiative transfer algorithm
18!     c) calls RTRN to do the radiative transfer calculation for
19!        clear or cloudy sky
20!     d) writes out the upward, downward, and net flux for each
21!        level and the heating rate for each layer
