EERIE Simulations
-----------------

The EERIE project (2023-2026) aims to quantify the role of ocean mesoscale processes in shaping the climate trajectory over seasonal to centennial time scales. EERIE develops a new generation of Earth System Models (ESMs) that are capable of explicitly representing a crucially important, yet unexplored regime of the Earth system – the ocean mesoscale. Leveraging the latest advances in science and technology, EERIE will substantially improve the ability of such ESMs to faithfully represent the centennial-scale evolution of the global climate, especially its variability, extremes and how tipping points may unfold under the influence of the ocean mesoscale.

**EERIE Models**

- `IFS-FSEOM2-SR <https://doi.org/10.26050/WDCC/EERIE_FESOM_hist_v1>`_
- `IFS-NEMO <https://doi.org/10.26050/WDCC/EERIE_NEMO_hist_v1>`_
- `ICON-ESM-ER <https://doi.org/10.26050/WDCC/EERIE_ICON_hist_v1>`_

**EERIE Experiments**

The main EERIE simulations are conducted following mainly the CMIP6 HighResMIP protocol and are only adapted with updates in forcings. E.g., the future scenario is based on the CMIP6 scenario ssp245 rather than the CMIP5 scenario rcp85.

**EERIE Data sources**

- The `eerie.cloud <https://eerie.cloud.dkrz.de>`_ provides a browsable interface using a EERIE stac collection. The STAC collection is a mirror of the intake catalog. Each STAC item is a dataset that contains Zarr access links as assets.
- The long term archive `WDCC <https://www.wdc-climate.de/ui/project?acronym=EERIE>`_
- `The CEDA Archive <https://data.ceda.ac.uk/badc/cmip6/data/EERIE>`_

A good starting point for starting to work with EERIE data is our `Hackathon github repository <https://github.com/eerie-project/EERIE_hackathon_2023?tab=readme-ov-file#simulations>`_.
