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, ...

2SUBROUTINE RRTM_CMBGB1
3!***************************************************************************
4
5!  The subroutines CMBGB1->CMBGB16 input the absorption coefficient
6!  data for each band, which are defined for 16 g-points and 16 spectral
7!  bands. The data are combined with appropriate weighting following the
8!  g-point mapping arrays specified in RRTMINIT.  Plank fraction data
9!  in arrays FRACREFA and FRACREFB are combined without weighting.  All
10!  g-point reduced data are put into new arrays for use in RRTM.
11
12!  BAND 1:  10-250 cm-1 (low - H2O; high - H2O)

14! ABozzo may 2013 update to the last version of rrtmg
