| # Bris-HourGlass |
|
|
| This repository contains the Bris-HourGlass (hourly temporal downscaler) checkpoints with matching training configs. |
|
|
| The intended use is training with Anemoi and forecast inference from the published model artifacts. |
|
|
| ## Contents |
|
|
| - `configs/Bris-HourGlass_o96.yaml`: global o96 pre-training config |
| - `configs/Bris-HourGlass_n320.yaml`: global n320 fine-tuning config |
| - `configs/Bris-HourGlass_stretched.yaml`: global+regional n320+2.5km stretched grid fine-tuning config |
| - `Bris-HourGlass_n320_inference.ckpt`: global n320 inference checkpoint |
| - `Bris-HourGlass_n320_training.ckpt`: global n320 training checkpoint (for further fine-tuning) |
| - `Bris-HourGlass_stretched_inference.ckpt`: stretched grid inference checkpoint |
| - `Bris-HourGlass_stretched_training.ckpt`: stretched grid training checkpoint |
|
|
| ## Scope |
|
|
| This is an artifact repository. It provides model weights and configs, but not input datasets. |
|
|
| The source code used for training is open and available through Anemoi Core: https://github.com/ecmwf/anemoi-core |
|
|
| ## Usage |
|
|
| Training is performed with the Anemoi codebase. |
|
|
| Training and fine-tuning of this model was done on the Anemoi Core branch `ecmwf/anemoi-core/tree/feature/ens_interp`. |
|
|
| https://github.com/ecmwf/anemoi-core/tree/feature/ens_interp |
| |
| Porting the checkpoints to a newer version is not supported, but the functionality in that branch is now all on the main Anemoi Core, so for training new models, using main is recommended. |
| |
| ## Notes |
| |
| - `bris-crpsfft_inference.ckpt` is the checkpoint intended for inference. |
| - `bris-crpsfft_training.ckpt` is kept as a training artifact. |
| - The configs are included to make the artifacts easier to interpret and reuse. |
