02 Call Digest

[jules32]

Hi all,

Thanks to NASA Openscapes Mentor Catalina Taglialatela from PO.DAAC for leading the Earthdata Cloud Clinic! The video is in our Cohort folder, the Jupyter Notebook we worked with in the JupyterHub also exists as part of our NASA Earthdata Cloud Cookbook (Earthdata Cloud Clinic) and that’s where you can see the commands she typed. 

Please continue experimenting in the Hub, and share/ask questions in the #2024-nasa-champions channel. We’ve also just sent calendar invites to (optional) Thursday Coworking sessions; you’re welcome to join in the weeks between our full Cohort Calls to work, screenshare, and ask questions. We’ll discuss data strategies and team culture next time to continue building our skillsets for the Cloud. Below is a light digest of Call 2.

Have a great weekend!NASA Openscapes Team & Mentors

Goals:

This clinic serves as a brief introduction to the NASA Earthdata Cloud, including how to work within a shared cloud compute environment, as well as how to find and access cloud-hosted data. A brief time together to get hands-on experience and experiment.

Task:

• Practice accessing NASA Earthdata in the CloudHave a Seaside Chat with your research groupPractice accessing NASA Earthdata in the Cloud:
  • Review the Clinic tutorial, try with other data. Next week we will discuss data strategies in the Cloud.
• Please ask any questions during Coworking or on Slack. 
• Coworking (optional): April 25. 10-11:30 PTA chance to work on your own things socially & ask questions/ screenshare. We share what we’re going to work on, and then work quietly and then check in at the end as well. We also make breakout rooms for Q&A if folks want to screenshare and talk things out.

A few lines from shared notes in the Agenda doc:

• NASA Earthdata Search - I accidentally put a space between 5 and day, totally different search results.
  • Very sensitive to these things, a known issue 
• Using earthaccess.search_data(), Can provide coordinates there as well, correct? 
  • Yes, and there is a bounding box example with coordinates further in the notebook
• Think of streaming data in the same way you stream video on Netflix or music over spotify; the data are stored in memory not on your hard disk. 
• What is a “granule”?
  • EOSDIS Glossary: “The smallest aggregation of data which is independently managed (i. e. described, inventoried, retrievable).
    • Granules may be managed as logical granules and/or physical granules.
    • A “physical granule” is literally one file
    • A “logical granule” may be multiple files representing one unit, e.g. a data file and metadata file.
• teaching tool is great approach, install and download problems otherwiseCost?
  • Erin: $100 for a workshop (30 people, 2-day workshop)
  • Matt: Another data point: $75, 25 people, 9-hour workshop
