FMS version 1 data type errors; no land points

[jr3cermak]

gridtools rel 0.3.3 does not work for building a small test problem for FMS version 1.0. Currently debugging proper data types for ocean_hgrid, mosaic and exchange grid files.

[jr3cermak]

Gridtools will create all three exchange files by default:

$ ncdump mosaic.nc 
netcdf mosaic {
dimensions:
	string = 255 ;
	nfile_aXo = 1 ;
	nfile_aXl = 1 ;
	nfile_lXo = 1 ;

 aXl_file =
  "atmos_mosaic_tile1Xland_mosaic_tile1.nc" ;

 lXo_file =

}

If there are no land points, gridtools should not create these exchange files.

FRE-ncTools:

Fix handling of tile variable so it is NC_CHAR type instead of string.

$ ncdump -h ocean_hgrid_t.nc 
netcdf ocean_hgrid_t {
dimensions:
	nyp = 9 ;
	nxp = 9 ;
	string = 5 ;
	nx = 8 ;
	ny = 8 ;

	char tile(string) ;

data:

 tile = "tile1" ;
}

With land points:

$ ncdump mosaic.nc 
netcdf mosaic {
dimensions:
	string = 255 ;
	nfile_aXo = 1 ;
	nfile_aXl = 1 ;
	nfile_lXo = 1 ;
variables:
	char atm_mosaic_dir(string) ;
		atm_mosaic_dir:standard_name = "directory_storing_atmosphere_mosaic" ;
	char atm_mosaic_file(string) ;
		atm_mosaic_file:standard_name = "atmosphere_mosaic_file_name" ;
	char atm_mosaic(string) ;

	char ocn_mosaic_file(string) ;
		ocn_mosaic_file:standard_name = "ocean_mosaic_file_name" ;
	char ocn_mosaic(string) ;
		ocn_mosaic:standard_name = "ocean_mosaic_name" ;
	char ocn_topog_dir(string) ;
		ocn_topog_dir:standard_name = "directory_storing_ocean_topog" ;
	char ocn_topog_file(string) ;
		ocn_topog_file:standard_name = "ocean_topog_file_name" ;
	char aXo_file(nfile_aXo, string) ;
		aXo_file:standard_name = "atmXocn_exchange_grid_file" ;
	char aXl_file(nfile_aXl, string) ;
		aXl_file:standard_name = "atmXlnd_exchange_grid_file" ;
	char lXo_file(nfile_lXo, string) ;
		lXo_file:standard_name = "lndXocn_exchange_grid_file" ;

// global attributes:
		:grid_version = "0.2" ;
		:code_version = "$Name: fre-nctools-bronx-10 $" ;
		:history = "make_coupler_mosaic --atmos_mosaic atmos_mosaic.nc --land_mosaic land_mosaic.nc --ocean_mosaic ocean_mosaic.nc --ocean_topog ocean_topog.nc" ;

}

There are two possible modes of operation. If it is known that no land points exist, we can exclude the --land_mosaic option and get a second possible solution.

Without land points:

$ ncdump mosaic.nc 
netcdf mosaic {
dimensions:
	string = 255 ;
	nfile_aXo = 1 ;
	nfile_lXo = 1 ;

	char atm_mosaic_file(string) ;
		atm_mosaic_file:standard_name = "atmosphere_mosaic_file_name" ;
	char atm_mosaic(string) ;
		atm_mosaic:standard_name = "atmosphere_mosaic_name" ;
	char lnd_mosaic_dir(string) ;
		lnd_mosaic_dir:standard_name = "directory_storing_land_mosaic" ;
	char lnd_mosaic_file(string) ;
		lnd_mosaic_file:standard_name = "land_mosaic_file_name" ;
	char lnd_mosaic(string) ;
		lnd_mosaic:standard_name = "land_mosaic_name" ;

	char aXo_file(nfile_aXo, string) ;
		aXo_file:standard_name = "atmXocn_exchange_grid_file" ;
	char lXo_file(nfile_lXo, string) ;
		lXo_file:standard_name = "lndXocn_exchange_grid_file" ;

// global attributes:

• Write test (expected failure) for regular grid with land but specify no land mosaic
• Write test for regular grid with land points
• Write test for regular grid without land points
• Write test for specifying a grid that does not have land points

Small toy grid problem proceeding further with fixes to the exp/rel033 branch.
