OPH_EXPORTNC

Description

Type

Data Process.

Behaviour

It exports data of a datacube into multiple NetCDF files.

Parameters

  • cube: name of the input datacube. The name must be in PID format.
  • schedule: scheduling algorithm. The only possible value is 0, for a static linear block distribution of resources.
  • misc: if “yes”, data are saved in session folder called “export / misc”; if “no”, data are saved within “export / nc” in a subfolder associated with the PID of the cube (default).
  • output_path: absolute path of the NetCDF output files. By default, all the files will be saved in session folder “export / nc / containerid / datacubeid”.
  • output_name: filename of the NetCDF output files. In case of multiple fragments, filenames will be “output_name0.nc”, “output_name1.nc”, etc. The default value is the measure name of input datacube.
  • cdd: absolute path corresponding to the current directory on data repository. It is appended to BASE_SRC_PATH to build the effective path to files (see configuration notes for further details).
  • force: flag used to force file creation. An existant file is overwritten with “yes”, whereas the file is created only if it does not exist with “no” (default).
  • export_metadata: with “yes” (default), it is possible to export also metadata; with “no”, it will export only data.

System parameters

  • exec_mode: operator execution mode. Possible values are async (default) for asynchronous mode, sync for synchronous mode with json-compliant output.
  • ncores: number of parallel processes to be used (min. 1).
  • sessionid: session identifier used server-side to manage sessions and jobs. Usually, users don’t need to use/modify it, except when it is necessary to create a new session or switch to another one.
  • objkey_filter: filter on the output of the operator written to file (default=all => no filter, none => no output, exportnc => no output).

Examples

Export data of the datacube identified by the PID “URL/1/1” :

[OPH_TERM] >>  oph_exportnc cube=URL/1/1;
