 ACE2-ERA5 is trained on the [ERA5 dataset](https://rmets.onlinelibrary.wiley.com/doi/10.1002/qj.3803) and is described in [ACE2: Accurately learning subseasonal to decadal atmospheric variability and forced responses](https://arxiv.org/abs/2411.11268).

+### Inference quickstart
+
+1. Download this repository. Optionally, you can just download a subset of the `forcing_data` and `initial_conditions` for the period you are interested in.
+
+2. Update paths in the `inference_config.yaml`. Specifically, update `experiment_dir`, `checkpoint_path`, `initial_condition.path` and `forcing_loader.dataset.path`.
+
+3. Install code dependencies with `pip install fme`.
+
+4. Run inference with `python -m fme.ace.inference inference_config.yaml`.
+
+### Strengths and weaknesses
+
 Briefly, the strengths of ACE2-ERA5 are:
 - accurate atmospheric warming response to combined increase of sea surface temperature and CO2 over last 80 years
 - highly accurate atmospheric response to El Niño sea surface temperature variability
