The GitHub repository of this work is at: https://github.com/yingkaisha/CREDIT-sigma-run

The FuXi models of this repository are modified from the original FuXi and developed at the 
NSF-National Center for Atmospheric Research (NCAR) for research purposes.

## Notes

To run the model, install the [CREDIT package](https://github.com/NCAR/miles-credit)
and modify the paths in the YAML configuration files. 

The datasets of the model will be prepared soon.
