FAQ

Using EAGLE

What platforms are currently supported?

At present, Ursa is the only supported platform for EAGLE, but support for additional platforms is coming soon.

Can I generate Anemoi training plots only for the nested HRRR domain?

Yes. Users can define multiple bounding boxes to specify subset regions, such as CONUS or Europe, by adding focus-area configuration to the PlotSample callback in the EAGLE pipeline base.yaml. This configuration generates plots that exclude the surrounding global domain. Define named boxes under focus_areas and reference the selected box from PlotSample with focus_area.

Although users can modify base.yaml directly for reference, it is recommended that they instead add the configuration to the eagle.yaml file created during the Quickstart workflow. Changes made directly to base.yaml may be overwritten during configuration composition, whereas updates made in eagle.yaml are preserved.

For example, for the HRRR/CONUS domain, use latlon_bbox: [22.0, -135.0, 50.0, -60.0] or adjust as needed. Once added, the diagnostics will generate plots restricted to the configured region. For more information, see the plot adaptor compatibility section of the Anemoi Training diagnostic documentation.

Can I add an HRRR-only variable, such as reflectivity, to nested-EAGLE training?

Not directly with the current nested HRRR-over-GFS training setup. The nested pipeline combines HRRR and GFS data into a single Anemoi training dataset, so the variables used for training must be compatible across the nested domains.

To train with an HRRR-only variable, users would need a CONUS-only configuration or a design that provides a compatible global counterpart, placeholder, or derived field, along with corresponding data, normalization, and model configuration changes.
