The repository declares no license file and GitHub's license endpoint returns 404, so it would be wrong to read the code as permissive. The only grant is the README's, and it puts the trained parameters under CC BY-NC-SA 4.0 and forbids commercial use, which caps the score at restricted whatever else was published.

  "The trained parameters of Pangu-Weather were made available under the terms of the BY-NC-SA 4.0 license" and "The commercial use of these models is forbidden"; links four downloadable ONNX checkpoints; states training needs about 60TB of ERA5 and 3000 V100 GPU-days per model; and ships inference_cpu.py, inference_gpu.py, inference_iterative.py and pseudocode.py.

  HTTP 404, "Not Found" - the repository carries no LICENSE file, so no repository-level grant exists to fall back on.
