! !MODULE:      METEO
!
! !DESCRIPTION: Routines to initialize/finalize meteo grids and data, allocate
!               datasets, and fill them. Include wrappers around read/write
!               meteo files.
!               Perform some meteo dependend calculations (omega, gph,
!               mass <=> pressure, ...)
!
!
! !REVISION HISTORY: 
!
!   09 Jun 2010 - P. Le Sager
!     - Fix in METEO_SETUP_MASS when reading restart files.
!     - Added some (protex) doc.
!     - Merge updates from EC-Earth project.
!   
!   10 Aug 2010 - Arjo Segers
!     - Reset previous fix since it gives differences after a restart.
!     - Use 'pw_dat' instead of 'mfw_dat' for massflux balancing;
!       otherwise 'mfw_dat' is changed by matching its values in a zoom
!       region with the parent, and this would give tiny differences
!       between a long run and two smaller runs with a restart in between.
!     - Reformatted protex comments.
!
!   10 Nov 2011 - Ph. Le Sager - adapted for lon-lat MPI domain decomposition
!   24 Oct 2013 - Ph. Le Sager - 6 new routines for parallel I/O
!
! !REMARKS:
!
!  (1) Several surface pressure fields are used:
!
!     sp1,sp2   : Surface pressures at begin and end of dynamic time step.
!                 Their values are interpolated between surface pressures
!                 read from the meteorological archive (in real(4) !) 
!                 or received from the meteorological model.
!                 Fields from the meteorological archive are stored into
!                 the 'sp2' structure, and copied from there into 'sp1'.
!
!     sp        : Actual surface pressure due to advection.
!                 In theory this field is equal to 'sp1' at the begin of a timestep,
!                 but due to numerical inacuracies ( real(4) vs real(8) )
!                 tiny differeces occur.
!                 Therefore, this field is stored and restored in case of restart.
!
!     spm         Surface pressure for the mid of the time interval,
!                 thus in between 'sp1' and 'sp2' .
!
!  (2) FIXME ZOOM : already coded, just need to check if it works as expected

    ! !REVISION HISTORY:
    !
    !   12 Mar 2010 - P. Le Sager - Fix when reading restart files. Added
    !                               protex doc. Added comments.
    !    9 Jun 2010 - P. Le Sager - Merged with updates for EC-Earth project.
    !
    !   10 Aug 2010, Arjo Segers
    !     Reset previous fix since it makes a restart different from a long run.
    !     Use 'pw_dat' instead of 'mfw_dat' since otherwise the later changed
    !     while matching a zoom region with its parent, and this would give
    !     tiny differences during a restart of a zoomed run.
    !     
    !    9 Nov 2011 - P. Le Sager - adapted for lon-lat MPI domain decomposition
    !
    ! !REMARKS:
    !
    !  push of Surf Press is done with sp2 (the only one on which we call
    !  setup -ie the only one for which %data1 and %data2 matter).  Only %data
    !  of SP and SP1 are updated and used, and not their %data1 and %data2.
