Interactive Activities

Each afternoon in the JEDI Academy, padawans will have the opportunity to work with the JEDI code in a series of hands-on activities. Each activity builds on those that precede it.

Consult the following pages for step-by-step instructions on how to proceed with each of these activities.

• Monday A: Getting Started with AWS, Singularity, and JEDI
  • Step 1: Icebreaker
  • Step 2: Access your AWS Instance
  • Step 3: Explore the JupyterLab Interface
  • Step 4: Download and enter the JEDI Container
  • Step 5: Get to know the Container
  • Step 6: Build fv3-bundle
  • Step 7: Explore the JEDI code
  • Step 8: Run the tests
  • Step 9: Save the test data
• Monday B: Running JEDI
  • Part 1: Simulating Observations like the JCSDA Near-Real-Time (NRT) Application
  • Part 2: Run DA Applications with FV3-GFS
• Tuesday A: Getting to know the variational application
  • Step 1: Download the data
  • Step 2: Revive your environment
  • Step 3: Run a 3DEnVar analysis for the C24 (4 degree model)
  • Step 4: Check that we produced a healthy looking analysis
  • Step 5: Improve the analysis
• Tuesday B: Adding new observations to be assimilated
  • Introduction:
  • Step 1: Save results from this morning
  • Step 2: Add a new ObsSpace to the 3DVar configuration
