Duo-Grid in GFDL's FV3: Code and Simulation Files for Cubed Sphere Testing

Supporting simulation files and code for the JAMES technical paper on implementing the novel Duo-Grid in GFDL's FV3 Dynamical Core. The study tests the implementation through idealized 2D and 3D simulations to address cubed sphere grid imprinting. The code is a test version compiled with FMS version tag 2020.04.

Use Cases

• Testing numerical methods for reducing grid imprinting artifacts based on the Duo-Grid concept described.
• Benchmarking the FV3 dynamical core's performance using the provided idealized 2D and 3D simulations.
• Reproducing results from the JAMES technical paper on cubed sphere grid implementations.
• Developing or validating new grid schemes for climate models based on the provided code structure.

Strengths

• Code and files are directly linked to a peer-reviewed JAMES technical paper, providing research context.
• The description specifies the code is compiled with a specific software version (FMS version tag 2020.04).

Limitations

• The description metadata is limited; actual data quality and file formats require manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred from the code and paper.
• The row count and dataset size are unknown, which may limit suitability assessment.
