How to limit the output to a single NetCDF file

  • for the folder of the input files, it depends of the input files :
    • for the restarts, you have the namelist variables cn_ocerst_indir, cn_ocerst_outdir
    • for file which are simply defined by their name (e.g. cn_domcfg = "domain_cfg") simply add the folder path in the file name (e.g. cn_domcfg = "MY_PATH/domain_cfg")
    • for the file read trough the structure definition :
  !           !  file name              ! frequency (hours) ! variable  ! time interp.!  clim  ! 'yearly'/ ! weights filename ! rotation ! land/sea mask !

use cn_dir in the corresponding namelist blocks

  • for the folder of the output files, see : How to change output folder?
  • to output from multiple processes confined into a single file
    • you need to use XIOS with the option type="one_file in your file_definition. See here and XIOS chapter in NEMO book
    • or use REBUILD_NEMO.
