INTERFACES

• added channel-selection to ObsSpace OSDF backend [SteveV and SteveH]
• benchmarking the ObsGroup vs OSDF in IODA after implementing a crude/temporary means to populated the OSDF from the ObsGroup. Benchmark is using mpas-jedi H(x) application, focus on cris and iasi instruments with many channels. [SteveH]
• enabling surface correction operator to handle geometry and geopotential heights as inputs [Raji]
• working on VADER LVCs to make more flexible (see PRs, including saber and fv3jedi adaptions) [SteveV]
• working on porting ectrans transforms to GPU [Liam]
• building JEDI repos on Nvidia compilers [FrancoisH]
• ongoing testing with Ricardo for improvements to the interpolations used with GSI-B in SABER [FrancoisH]OBS -

OBS

• The 2nd ROMEX meeting took place in Darmstadt at EUMETSAT.
• Presenters from all partners (NOAA, NASA, NRL & JCSDA participated in the meeting.
• JCSDA (Hailing) presented results with the JEDI-based system. 

UFO

• Mike Cooke’s PR #3610 has added the first leg of few PRs to complete varBC by record.  We need this reviewed by the impacted partners NOAA and NASA.
• Nghi Do for from Scripps UCSD had a fix with an ROPP Airborne Radio Occultation ctest is not routinely exercised and had fallen behind.
• JianJun has a series of PRs for all-sky implementation. The 1st one was merged to get potential temperature at selected levels. There are additional PRs, one in fv3-jedi, one on IODA conventions, and a third one adding a ctests of the function related to the cloud fraction calculations. Please review those PRs if you’re interested.
• Praveen from NOAA has a PR to bring in Eumetsat Cloud and Aerosol Detection code in JEDI. That code was originally written by Andrew Collard.
• Ricardo has a PR to provide options to set CO2 for passing into CRTM.  A constant which can be defined via yaml, or to enable a global Constant based on an equation derived from data at Mauna Loa. We are reviewing this and requesting the activation of the Mauna Loa feature and the addition of a ctest.

CRTM

• The CRTM team is participating in the VIS/UV DA workshop held in Italy this week.
• Pending PR on unit tests regarding surface emissivity currently under review.
• Bug/issue regarding surface emissivity jacobians (V3.0+, reported by Jack Liu)
• CRTM k-matrix unit test failures with intel compiler (reported by Evan)

COMPO

• NASA presentation to the Earth Science Directorate about our TEMPO success
• ISSI presentation about our advances in Visible L1b data assimilation
• R2D2 discover switch to CSS
• first set of TEMPO DA runs for publication finished
• Help on aerosol dependency with SOCA OASIM development

SOCA

• Travis has been working on general SOCA code optimization and AI based covariances
• Kriti has been working on scientific testing of HTLM and having some issues which Christian is helping with
• Discussion with Hernan: Travis plans on adding vertical impicit diffusion next AOP.
• Hamideh has been working on wrapping her OASIM PRs

ALGO

Nate

• merged PR in MPAS-JEDI and Skylab for using the CCPP model variable names with MPAS (a big thanks to BJ for his help with this)
• fixed the MPAS 120km static B Skylab experiment (it needed a new background generated from the version of MPAS in the jedi-bundle). The new background will be ingested into r2d2 soon.
• ProcessPerts for multi-scale localization is now in EWOK & Skylab.
• Working on a fix in saber for letting process perts work better when increment includes surface fields.

Christian

• Adding adaptive regularization and SVD truncation options to the HTLM. Testing with SOCA and GEOS
• Testing Skylab additions for continuous DA
• Slowly working to get single stream MPAS in Skylab
• Continuing on continuous DA code changes in OOPS.

Clémentine

• Doing some testing of our skylab experiments with spack 1.9.1
• Narrowing down (?) on convergence issues with GEOS variational, debug mode failures from Dan, ... and other fv3jedi subtleties
• Testing gsi 4denvar with Ricardo
