   CMORization
      The process of rewriting model-specific output files for model intercomparisons (MIPs) using
      the ``cmor`` module. Named after the CMOR (Climate Model Output Rewriter) library.

   CMOR
      Climate Model Output Rewriter. A library maintained by `PCMDI <https://cmor.llnl.gov/>`_ that
      rewrites climate model output into a standardized format for model intercomparison projects.

   MIP
      Model Intercomparison Project. A coordinated effort to compare climate models (e.g. CMIP6, CMIP7).

   MIP table
      A JSON configuration file that defines variable metadata requirements for a specific realm and
      frequency combination (e.g. ``CMIP6_Omon.json`` for ocean monthly variables).

   controlled vocabulary
      A standardized set of allowed values for metadata fields such as ``experiment_id``,
      ``source_id``, ``grid_label``, and ``nominal_resolution``. Published by the CMIP community.

   variable list
      A JSON file mapping modeler variable names to MIP table variable names. Generated by
      ``fremor varlist`` and consumed by ``fremor run``.

   experiment configuration
      A JSON file containing experiment-level metadata required by CMOR (e.g. ``experiment_id``,
      ``activity_id``, ``source_id``, institution information, variant labels).

   target
      The compilation option passed to ``fre make`` (e.g. ``prod``, ``repro``, ``debug``).
      Supplementary options may be appended with ``-`` (e.g. ``prod-openmp``).

   platform
      The computing platform and compiler specification (e.g. ``ncrc5.intel25``, ``gfdl.intel25``).

   FRE
      Flexible Runtime Environment. GFDL's framework for compiling, running, and post-processing
      climate models.

   FMS
      Flexible Modeling System. GFDL's software framework for building and running Earth system
      models.

   pp directory
      Post-processing directory. The root directory containing per-component subdirectories of
      post-processed model output (e.g. ``/archive/user/experiment/pp/``).
