Let’s Start with Some Motivation – A Case for Open Science

SETTING THE THEME FOR THE WEEK…

What is Open Science in practice?

Open Data + Open Algorithms + Open Software + Open Peer Review + Open Access Publication

Thereby, science process and outputs can be:

• Transparent
• Reproducible
• Transferrable
• Collaborative
• Credible!
• Durable, sustainable

IMPORTANT!

No conflict between Intellectual Property Rights (IPR) and licensing.

Who is a scientist?

• Affects incentive structures: who can and should receive credit for publishing not only papers but also data sets and code.
• Career progression, opportunity

Open science solutions – pro tips (1/2)

1. Use Git for collaborative change/version code management
• GitHub: github.com
• GitLab: gitlab.com
2. Use binder where possible!
• Easy way to share your notebooks + environments with others
• Good for development, even while traveling
• Many freely available options – including Project Pythia (https://binder.projectpythia.org/)
3. If you have a choice, use an open programming language (ex. Python)

Open science solutions – pro tips (2/2)

3. Avoid proprietary algorithms like Numerical Recipes
4. Publish code
5. Publish data
6. Publish code & data associated with a study/paper

How? (next slides)

7. Publish in Open Access journals

Let’s Get Back to ARM – Open-Source Software!

An Introduction to the Python ARM Radar Toolkit�(Py-ART)!

• Initially created by Scott Collis + Jonathan Helmus (2012), funded by the Department of Energy Atmospheric Radiation Measurement user facility.
• Over 300 citations of the package, 1000’s of monthly users. Engineered as a community package.
• Used for both operations and research across the globe.
• Now: Pivot to using xradar as the IO layer backend.

An Introduction to the Atmospheric Data Community Toolkit (ACT)

• Initially created by Adam Theisen in 2019
• Built for exploring and analyzing time-series-based atmospheric research datasets
• Includes tools for the whole research lifecycle
• Data discovery
• Quality-control
• Data visualization
• Output to standard formats
