Shutdown status: Only contractors & university co-ops working.
Ricardo (pre-furlough):
Multi-outer-loop tests suggest UFO filters may not apply in later loops unless a specific switch is enabled (switch name TBD). Question: set True by default?
Observed outer-loop state updates not propagating correctly due to SWELL workflow setup (investigating).
Marine: Extensive local coupled-model testing; R2D2v3 now being tested in SWELL.
Onboarding: Helping Jerome and Maryam with SWELL; leveraging their R2D2 experience; interest in EVA (relevant to EMC).
cylc in Skylab: Progressing; toy models under test (Ashley).
R2D2: Cleaning client/server technical debt & maintenance (Eric).
spack-stack: Feature branch with Dom’s Spack 1.0 integration; basis for spack-stack 2.0 (target early Nov) (Evan).
CI: Intermittent issue affecting 5–10% of builds with excessive timeouts under troubleshooting (Evan).
Parallel covariance models: Plan to modify ECTRANS to manage multiple split MPI communicators so ensemble waveband B models can run in parallel (currently sequential in hybrid-B causing IO/compute overhead).
4D-Var: Focused on speed-up; current initial setup slow (mixed known/unknown causes).
Regional JOPA: Observation configurations nearly ready for final trials.
IODA converter PR-1701 (MRMS): Code fixed; smaller files.
UFO: Surface operator GFS operator — possible interface issues flagged.
Unified Super Operator: Open question; Ricardo / François V. associated.
Sea-ice model investigation ongoing.
NWS exempt from furloughs.
JEDI R&D / Real-time: Two real-time “upgradeS” GFSv17 full-res parallels; GCAFS (aerosols) repo: https://github.com/NOAA-EMC/GCAFS.
Retrospectives: Start end of month; science freeze for retro; 2 hurricane seasons; ~6 months to generate. Large res + ocean increases compute.
Obs format for JEDI ingest: Finished.
Regional: Background error model work; PR in SABER to turn on all testing for GSI-BEC.
HAFS-JEDI: Running real-time for multiple storms.
Optimization: With GDIT; NetCDF chunking for HAFS and RRFS.
spack-stack 1.9.2 working well; switching to it.
Static spectral B: Multithreading completed; next: waveband ensemble B, variable changes, HTLM for next deliverable.
OSDF-based reader: Progress; expect load step done this sprint.
CO₂ units fix: Model-interface → GeoVaLs → UFO standardized to mol/mol.
obs2ioda: yaml-cpp replaced with eckit.
Fortran allocatables & methodology: Memory not released in some paths; need disciplined allocate if not allocated / deallocate pattern. Will discuss with Benjamin M.
Apple M4 (12-core): ctests run very fast.
