.. _models_simulations_intro: Climate Models ============== The Climate DT comprises three coupled atmosphere–ocean models: :ref:`icon`, :ref:`ifs_fesom`, and :ref:`ifs_nemo`. Each runs at approximately 5 km to 10 km atmospheric resolution, with ocean components at varying resolutions depending on the model. Each uses a different native grid, but output is interpolated onto a common HEALPix mesh and harmonised using a Generic State Vector (GSV) for consistent access across all three models. For the full inventory of available simulations, see :ref:`simulations`. .. toctree:: :maxdepth: 1 ICON/index IFS-FESOM/index IFS-NEMO/index
