source: LMDZ6/trunk/libf/dynphy_lonlat/phylmd/etat0dyn_netcdf.F90 @ 4241

Last change on this file since 4241 was 4050, checked in by dcugnet, 3 years ago

Second commit for new tracers.

  • include most of the keys in the tracers descriptor vector "tracers(:)".
  • fix in phylmdiso/cv3_routines: fq_* variables were used where their fxt_* counterparts were expected.
  • multiple IF(nqdesc(iq)>0) and IF(nqfils(iq)>0) tests suppressed, because they are not needed: "do ... enddo" loops with 0 upper bound are not executed.
  • remove French accents from comments (encoding problem) in phylmdiso/cv3_routines and phylmdiso/cv30_routines.
  • modifications in "isotopes_verif_mod", where the call to function "iso_verif_tag17_q_deltad_chn" in "iso_verif_tag17_q_deltad_chn" was not detected at linking stage, although defined in the same module (?).

1MODULE etat0dyn
2!
3!*******************************************************************************
4! Purpose: Create dynamical initial state using atmospheric fields from a
5!          database of atmospheric to initialize the model.
6!-------------------------------------------------------------------------------
7! Comments:
8!
9!    *  This module is designed to work for Earth (and with ioipsl)
10!
11!    *  etat0dyn_netcdf routine can access to NetCDF data through the following
12!  routine (to be called after restget):
13!    CALL startget_dyn3d(varname, lon_in,  lat_in, pls, workvar,&
14!                          champ, lon_in2, lat_in2)
15!
16!    *  Variables should have the following names in the NetCDF files:
17!            'U'      : East ward wind              (in "ECDYN.nc")
18!            'V'      : Northward wind              (in "ECDYN.nc")
19!            'TEMP'   : Temperature                 (in "ECDYN.nc")
20!            'R'      : Relative humidity           (in "ECDYN.nc")
21!            'RELIEF' : High resolution orography   (in "Relief.nc")
22!
23!    * The land mask and corresponding weights can be:
24!      1) already known (in particular if etat0dyn has been called before) ;
25!         in this case, ANY(masque(:,:)/=-99999.) = .TRUE.
26!      2) computed using the ocean mask from the ocean model (to ensure ocean
27!         fractions are the same for atmosphere and ocean) for coupled runs.
28!         File name: "o2a.nc"  ;  variable name: "OceMask"
29!      3) computed from topography file "Relief.nc" for forced runs.
30!
31!   *   There is a big mess with the longitude size. Should it be iml or iml+1 ?
32!  I have chosen to use the iml+1 as an argument to this routine and we declare
33!  internaly smaller fields when needed. This needs to be cleared once and for
34!  all in LMDZ. A convention is required.
