# SoPhAr aviation: data, results and figures

Data, model results and figures for *Solar phased-array-based wireless power transfer for commercial
aviation decarbonization* (T. Wang, Y. Xu, J. Byeon, J. Jiao, J. Mohammadi, K. Kockelman, C. Claudel
and A. Bayen; under review at *Nature Sustainability*). The code is at https://github.com/BonnyWang010705/SoPhAr.

## Using the dataset with the code

Download the dataset into the root of the code repository:

```bash
python download_data.py      # run inside the cloned code repository
```

`data/`, `results/` and `figures/` then sit next to `code/`, where every script looks for them.
