guide_p_mod.F90 @ 3536

Last change on this file since 3536 was 1416, checked in by jghattas, 14 years ago

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 use_filtre_fft=n).
the results are the same as the sequential mode in previous revision.
test done only with guide_u=y,guide_v=y

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