Following bug corrections are already done at branch LMDZ4_AR5 rev
1417,1416 :

Bug corrections for nudged run (pres2lev.F90, guide_p_mod.F90) :

  • now the results are the same for sequentiel and parallel mode(if adjust=n and compiled with vsafe at mercure).
  • the results are the same as the sequential mode in previous revision.
  • test done only with guide_u=y,guide_v=y
  • copied optimized version of pres2lev.F90 from dyn3dpar to dyn3d


Added condition read_climoz for the variable O3daySTD(calcul_STDlev.h,
undefSTD.F)

Corrected bug in calculation of the diagnostic variable ec550aer
"Extinction at 550nm" (aeropt_5wv.F90) (Maria Raffaella Vuolo, LSCE)

Added stop if use_filtre_fft=y with dyn3d (conf_gcm.F) : this option is
not implemented in dyn3d.
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
