Sample Data¶
Pre-sliced files ship with each tutorial repo — for example, extract-point/data/.
Full access instructions and attribution requirements are in DATA_SOURCES.md on GitHub.
Dependencies¶
Each tutorial repo pins its own requirements.txt or environment.yml. Check the tutorial repo before running locally or in Colab.
New to This Stack?¶
Start with the Point Extraction tutorial — it uses ERA5 sample data included in the repo. No API key required to run the notebook.
