INFRA
- IODA parallel reader - first functional version ready for testing around next week
- R2D2 interface improvements, kwarg validation soon, can relocate r2d2-experiments-localhost
- spack-stack - jedi - hercules - fckit shared pointer issue
- boost regex issue need to revert oops PR
- CI pipeline - found bug in caching; if errors found (old CI passes, new CI fails) please notify jedi-infra through the usual channels and tag @eap in the PR
- EWOK ingest suites for observations is progressing nicely, more and more obs types are added
- Dom on leave for the next three weeks
- use jedi-infra-support slack channel, jcsda-internal discussions, or forum; please avoid contacting individuals in the team directly
ALGO
- Merging code today that removes variable-change-to-anaylsis-and-back code - NEED DETAILS FROM ANNA
- Next Monday: Merge PR from Mayeul that may affect certain ctests - NEED DETAILS FROM ANNA
- Coming soon: PR to pass parameters through configurations instead of interfaces
- Coming soon: PR global interpolator replacing atlas interpolater,m affecting saber interpolator bock
- Need yaml change: key to switch interpolator
- Ricardo: Why the default can't be what it is now?
- Anna: The default depends on the situation/application, and previously one or the other was used (hardcoded); now you can switch for either of them.
- Hernan: Problem with interpolator with models on staggered grid
- Yannick: Decision was made in the past that model passes all variables on the same grid to avoid the complexity of dealing with different staggered grids in different models
- Dan: Can't interpolate winds on staggered grids, because they are tangential to the grid - requires rotation (too much to ask from generic code)
- Yannick working on improvements on 4denvar, Anna using that information for cross-covariances
- Bug fixes in bump concerning sampling in limited area models, new nicas normalization otion
- Progress on MPAS-Skylab
- Finalization of jedi-atlas interface requirements document
COMPO
- geos-cf cycling PR soon
- adding tracers to linear model
- tempo converters (series of PRs to integrate tempo data - for proxy data for now)
- omps suite of converters and others -
- CCPP standard names PR for new names from composition
- Shiwei - working on using metplus to get score cards at JCSDA
- Emily Liu: EMC wants to adopt column ... for ozone?
MARINE
- Planning meeting for soca for this quarter
- Kriti: Evaluating qc for in-situ salinity profiles within Skylab
OBS
Ingest
- Work with INFRA on ingest suite
- EMC working on converters for all their bufr dump converters; JCSDA developed their own converters (some originally coming from NCAR), verifying against EMC converters, sharing back with MMM
- IODA meeting on July 19 (see IODA issue 1058): requesting groups of variables in obs space that shouldn't go to the output file (because only used internally etc.)
- Greg's upcoming change for ioda-converters, UFO: sensor scan position must be integer in the file (is float now)
- Need to convert and re-ingest about 6000 files in R2D2
- Met Office confirmed that they are ready, will need to verify with other centers
- If no issues raised, may merge next week
UFO/OBSPROC
- Work on supporting different versions of CRTM within UFO develop, because partners use JEDI for their own verification but older versions of CRTM
- CI/develop tests must support two versions of CRTM (detects CRTM version), coming soon
- Variational BC for conventional (non-channel-dependent) data types (mostly aircraft for now)
- Planning on code sprint in the week of Sep 11, scope will be worked out this/next week
- Incorporating features from GMAO on ????? operators; making sure that generic code is working with specific parameters from GMAO
- Proposal PR ready today or tomorrow
CRTM
- v3 occasional underflow values in tests; fixed by forcing initial allocation to be zero (array being passed in and out of several routines)
- resolves long-standing problem with intermittently failing tests
- going through rest of code to identify similar issues (has a slight impact on performance)
- Getting sea surface emissivity model over from v2 to v3
- Working on radar PR from Isaac (massive PR)
- Expect changes in test references for v3 as elements of 2.4.1 are brought over
- Land surface emissivity changes in v3 lead to colder temperatures at surface, taking a closer look at land surface emissivity model
- JCSDA land lead one appointed needs to take over this work
- Patrick Stegmann leaving JCSDA, will be available for some time to answer questions around coefficient generation
- NESDIS star taking over some of the coefficient generation, new position at JCSDA will be opened soon
EMC
- Bugs related to B matrix calculation in SOCA (linear variable changes instead of SABER blocks)
- Increment off by a factor of two, trying to replicate in fv3-jedi since can't find bug in SOCA
- Anna: UK Met Office may have had the same problem, they fixed it but how?
- Olly: Problem was entirely on Met Office, bug in their code
- Ricardo: GSI increments may be wrong/half? But Guillaume has a simple test that shows that increment in SOCA is wrong (Dirac test)
- Once GPSRO UFO code ready, please notify EMC so that they can test it
Met Office:
- Observation processing: four types of global obs left, at least three to be ported in September
- ODB working on all variables in the obs space
- DA method: hybrid B progressing well, hold vertical level information and interpolate between saber blocks
- faster/simpler spectral cov calibraiton
- HTLM oops PR for hybrid linear model restructuring, optimizing ..., allows training of ... ?
- simplify linear model time step (factor of hybrid lin model time step)
- Control pert PR: responded to comments in PR, once approved will implement operastor in model ... control
- Cycling 3dvar w/ limited obs types
GMAO
- Matching GSI observation operators with CRTM v2.4, halfway done
- Using on-premises CI system: nightly run to build whole JEDI system to test UFO operators
- EVA work: code sprint in a few weeks on documents etc.
- Working on cycling ... (Ricardo) - PR to come, including GSIbec update
- should have a spack-stack update for that
ROMS
- Interested in BUMP features, but documentation is a disaster and debugging is difficult
- Many switches, flags with meaningless names
- Problems with isotropic correlation training
- Writing coefficients to ??? fails, bump not leveraging netCDF metadata information
- Debugging is difficult because bump is using Python (?) preprocessor
- Recommendation is to run separate preprocessor step in cmake and load those
- Analyzing sea-surface salinity
- Analyzing critical older 3dvar algorithms and porting to 4dvar
NRL
- Dual-resolution work progressing, IODA v3 converters merged, cylc suite improvements, adding diagnostics, evaluating iasi and metopb, ongoing HPC issues that have slowed things down
MMM
- Experimenting with letkf in mpas-jedi. Crashes when assimilating GNSSRO data, works fine in 4denvar
