Notes from JEDI meeting 5/25/2023

Yannick Opened with two Announcements:

• After discussion at JCSDA Science Workshop, partners will now give updates at this JEDI meeting, in addition to the core team leads.
• Code changes that have impact across repos will now be announced in a new way, via the "Discussions" tab on the "JCSDA-internal" organization page:
  • https://github.com/orgs/JCSDA-internal/discussions
  • There are different categories for the discussions, seen on left sidebar of the Discussions page.
  • Be sure to click “Follow” on the JCSDA-internal organization page so you receive notifications of new discussions.

INFRA-Dom

• Making progress on EWOK-CI
• Spack stack 1.4.0 almost rolled out.
• There's a new version of HDF5. Can’t use mpich older than 4.0.3
• Theres a new Jedi-infra-support slack channel. If someone doesn't have access they can also use the new Discussions page (INFRA Category) on JCSDA-internal.

ALGO-Anna

• Atlas & eckit changes are in ECMWF repos but require c++ 17, so need to wait for that rollout to JEDI repos.
• Work in VADER will soon introduce a new model Traits class for ModelData. Watch for more information.
• JEDI EDU was used and went really well. Positive comments from Peter Jan van Leeuwen.

COMPO-Jerome

• Running hofx. Working! Unexpected.
• Vertical levels are flipped. Need to work on that.

OBS-Hui

• During testing found some filters need to be fixed so they can be used without bias correction
• Merging some PRs. 
• CRTM 2.4.1 now in develop.
• IODA converters. Work with EMC and NCEP decoder.
• Setting up Skylab experiments

CRTM-Ben J.

• Working on CRTM v3 test in UFO. Getting close to rolling that out.

Marine-Kriti

• No updates due to lots of team PTO

EMC-Cory

GMAO-Ron Gelaro

• Work on Obs Configuration. Down to Marine Surface Wind. That finishes conventional obs.
• Still struggling with 4D issues. Might be an incompatibility with the JEDI 4D cost function?
• Working on Spack-stack compatibility
• Getting Dom NCCS account.

Met Office-David S.

• Very close to surface obs done on UFO
• Marek going to work with Steve H. to improve IODA input performance
• Marek working on hybrid covariance
• Looking at problem with increment being off by a factor of 2. Anna investigated and thinks there's no issue in FV3. (Apparent "problem" there is because test was between two grid points.) Anna thinks issue is in Lfric-lite, so Met Office will keep investigating.

NRL-Sarah

• Working on new obs. GNSSRO
• Spinning up new HPC’s.
• 3dvar fgat cycling test

NCAR-MMM-Jake

• Working on All-sky ATMS assimilation.
• Looking at bad q (moisture) analysis in stratosphere
• Looking at CRTM problem with Jacobian magnitude

ROMS-Hernan

• Recently presented on JEDI in Rome.
• Dealing with ifort compiler issue with BUMP in their environment.
