PO.DAAC Learning Resources
Learning resources created by NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC) help users find, analyze, and visualize data.
The PO.DAAC cookbook is a repository of tutorials designed to help users learn about and experiment with datasets.
Resources include:
- How-to section: bite-sized pieces of code
- Tutorials: example workflows specific to PO.DAAC datasets
- Advanced Cloud resources: guides, recipes, and more to help optimize cloud workflows
- Tech Guide: instructions to clone the PO.DAAC repository
