PROGRAM PREP_NEST_PGD
! #####################
!
!!**** *PREP_NEST_PGD* - to make coherent pgd files for nesting
!!
!! PURPOSE
!! -------
!!
!! The purpose of this program is to prepare pgd files with which
!! nesting can be performed. A pgd file must be coherent with its
!! father:
!! The average of orography of fine model on each of its father grid
!! mesh must be the same as its father orography.
!!
!! All the pgd files are read at the begining of the program,
!! then they are checked, and recursively, the orography of a father
!! is replaced by the averaged orography from ist son.
!!
!! The control data are given in the namelist file PRE_NEST.nam
!!
!! &NAM_NEST_PGD1 CPGD='coarser model' /
!! &NAM_NEST_PGD2 CPGD='medium model' , IDAD=1 /
!! &NAM_NEST_PGD3 CPGD='medium model' , IDAD=1 /
!! &NAM_NEST_PGD4 CPGD='fine model' , IDAD=2 /
!! &NAM_NEST_PGD5 CPGD='fine model' , IDAD=2 /
!! &NAM_NEST_PGD6 CPGD='fine model' , IDAD=3 /
!! &NAM_NEST_PGD7 CPGD='very fine model' , IDAD=6 /
!! &NAM_NEST_PGD8 CPGD='very very fine model' , IDAD=7 /
!!
!! In each namelist is given the name of the pgd file, and the number
!! of its father. This one MUST be smaller.
!! There is one output file for each input file, with the suffix
!! '.nest' added at the end of the file name (even if the file has not
!! been changed).
!!
!! In the case of the namelist above, one obtain something like:
