radiation_flux.F90 @ 5411

Last change on this file since 5411 was 4728, checked in by idelkadi, 14 months ago

Update of ecrad in the LMDZ_ECRad branch of LMDZ:

version 1.6.1 of ecrad
files are no longer grouped in the same ecrad directory.
the structure of ecrad offline is preserved to facilitate updating in LMDZ
cfg.bld modified to take into account the new added subdirectories.
the interface routines and those added in ecrad are moved to the phylmd directory
