Observation vector (:bash:`obsvect`)
------------------------------------

Currently, only one plugin is available for :bash:`obsvect`. For the first simulation, no previous file is read, but the file generated by the simulation is saved for use in later simulations.

.. code-block:: yaml

  obsvect:
    plugin:
      name: standard
      version: std
    dump: True

If all the :bash:`monitor.nc` files to use for comparison are ready and organized in a directory with sub-folders by type (e.g. ``OMI``, ``IASI``) and then by species (e.g. ``CH4``, ``N2O``), you can simply provide the root directory here.

.. code-block:: yaml

  obsvect:
    plugin:
      name: standard
      version: std
    dump: True
    dir_obsvect: directory_with_perfectly_ordained_and_formatted_monitor_netcdf_files/


If the directory structure is incorrect or files are not named ``monitor.nc``, the information will not be used. In most cases, observation data is therefore provided in :bash:`datavect` via the dedicated components.

The requirements for the standard obsvect are :bash:`model` and :bash:`datavect`.
