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, ...
