Last change on this file since 4993 was 4728, checked in by idelkadi, 13 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
