Combining the output data
When NEMO executes, each processor writes out the particular part of the ocean
on which it operated to a separate netCDF (.nc) file. In order to
perform any analysis or verification of the output data these netCDF files
must first be recombined into a single netCDF file on which the viewers (e.g.
nemoplotnc, ncview etc) and diagnostic tools (e.g. CDFTOOLS) can operate.
The nocscombine code can be used to perform this recombination. To
recombine a series of netCDF 3.6.2 files using nocscombine the
following command can be used:
nocscombine -f O25-TST_CU30_19580101_19580101_grid_T_0000.nc -d votemper
The -f specifies the file series which is to be recombined, the
-d specifies the particular field (e.g. temperature, salinity,
velocity etc) that you wish to extract. If no -d is specified
then the entire netCDF file will be recombined. The default output file name
will be as given to the nocscombine tool with the processor number
stripped away, e.g. O25-TST_CU30_19580101_19580101_grid_T.nc for
the example above. If required, the output file can be altered with the
-o flag. The options for nocscombine can be viewed with
the nocscombine -h command.
