JEDI weekly meeting notes


Andy/Land:

In terms of preparation for the release:

  • Two lots of observations are in R2D2

  • Ewok YAMLs are under review

  • Have to change long names in FV3-Jedi for soil moisture to match observation name, that PR is in too.

On the side, I’ve been trying to sort out the ATLAS interface changes from a few weeks ago with the WRF-Hydro interface

Jerome/COMPO:

- The goals for the skylab1 release are completed
- We can run H(x) with GFS-aerosols with VIIRS AOD using EWOK and R2D2

Travis/SOCA:

- Hamideh working on ocean color forward operator, OASIM, will be integrated into UFO in the next couple of months
- Kriti: ensemble DA experiments with regional ocean domain
- Travis: wrapping up skylab integration, I just need to gather all the data files, submit the required PRs, and coordinate with Eric to get the files where they belong.
- Also, we are still dealing with problems from the GetValues refactoring that was done several months ago, leaving our develop branch unusable for realistic workloads. I'm coordinating with Francois H to hopefully get a fix in OOPS very soon.

Patrick/CRTM:

Tropics is available now. Antaris did not make it to orbit. He already mentioned the UFO code sprint and the minor issues getting tests to run on Orion. Issue with kernel installation there. At CRTM monthly meeting, we will have invited speaker about cloud project from Europe.

Ben,Hui/OBS:

  • OBS team is testing CRTM2.4 for a potential release with UFO.
  • The preliminary results show differences with current UFO tests with CRTM2.3.
  • Currently OBS team is working on identifying the source of the differences.
  • One change from CRTM2.4 is that CRTM2.4 would simulate clear sky radiance once cloud_fraction is less than a minimum threshold, which is different from CRTM2.3. This would affect the sensors using the cloudy radiance. 
  • OBS team is communicating with CRTM as well as EMC team, who confirmed the differences.
  • There are also other changes/bug fixes from CRTM2.4 and their impacts are not yet clear on UFO tests.

Dom/Infrastructure:

- eckit/fckit/atlas issues tracked down to version mismatches when building atlas-0.29 in jedi-stack
- spack-stack release candidate 2 created 2022/06/23, expect final release next week
- Dom currently rolling out on target platforms: Discover (Intel,GNU), Orion (Intel, GNU), AWS Red Hat 8 / Ubuntu 20.04 (GNU), macOS (clang+gfortran)
- Includes everything to build jedi-fv3/mpas/um/ufs/-bundle, soca-bundle, ewok
- Figuring out a few last details for building certain packages
- Need to know if the JEDI release should provide default/reference versions for solo, r2d2, ewok or not (i.e. users always have to install themselves)
- NASA requested adding packages to spack-stack to build GEOS, use on Discover
- Great opportunity to get NASA software developers join spack-stack effort and get help with GEOS build
- Work on automated CI testing of EWOK using Github self-hosted runners
- Include testing feature branches of bundle and its components together automatically
- Not cloning whole bundle every time, just check for updates of existing clone and run
- Wrapping up R2D2 and EWOK work for release, new model for aerosol GFS backgrounds, added observations for land in R2D2, install Python simobs Python library
