- JCSDA-internal and JCSDA github organizations will require Github 2FA beginning of October
- https://github.com/orgs/JCSDA-internal/people?query=two-factor%3Adisabled
- https://github.com/orgs/JCSDA-internal/discussions/64
- Does only affect logging into github and performing security-relevant options, not day to day work
- Users who don't have 2FA enabled by then will automatically be removed from the organization
- Heads up: we will do the same for our AWS accounts in the future
- ioda parallel reader PR ready for testing
- https://github.com/JCSDA-internal/ioda/pull/1071
- Caveat: can't write to single file (hangs; investigating), workaround is to switch to write to multiple files, see description in PR
- Work continues on the ingest suite and the new CI system (onboarding more repositories this/next week)
- Resumed work on spack-stack to prepare for the release Sep 9+/-
- Includes new bufr@12 library
ALGO - Anna
Nate Crossette joined JCSDA last week to work on the background error covariances.
Upcoming updates:
- Change in yamls when specifying forecast output (steps now are durations; new key times): https://github.com/orgs/JCSDA-internal/discussions/63 (merge today)
- Passing configuration instead of Parameters through model interfaces: https://github.com/orgs/JCSDA-internal/discussions/55 (merge August 22nd)
- Francois will announce today, in the Github discussions, the first change to do as part of the atlas interfaces; simple renaming things. We'll merge that in two weeks.
Development:
- 4D covariances (4DEnVar and weak constraint 4DVar): refactoring of saber block chains to be merged this week (shouldn’t affect model interfaces, although small effect on lfric-lite-jedi). Coming up: passing 4D fieldsets to the block chains. Next week: handling cross-time covariances and localization in saber.
- Merged: option to write out eigen vectors in lat-lon format.
- Merged: capability to read and write HTLM coefficients to and from disk (with MetOffice)
- Kate is making good progress on the control Pert EDA app, we have been finding and fixing issues this week. The workflow is ready for when we have a reasonable app to test.
- Clementine revived 3DFGAT-UFS branches with latest develop / changes
- Looking into how we can use the new Atlas changes to simplify and speed up HTLM (with MetOffice)
- Ongoing work on mpas-skylab, EDA comparisons, atlas interfaces, B training workflow.
OBS - Hui
Changed sensor scan from float to int
Start enforcing naming convention sometime soon
Working with Clara Draper on snow coverage
BUFR PR will be helped by new spack-stack

Getting VarBC working
Hope to have working branch before code sprint week Sept. 12
Radiance converted to Brightness Temp work
Also, getting Romex working with RO. Working with Skylab
CRTM - Cheng
CRTM v3 PR with snow emissivity coefficients
Notice need to run CRTM standalone, so working on that.
Ben is testing coefficients.
Trying to hire to backfill Patrick Stegman’s position

Maryam is working on something (sorry, missed this - STV)
Placeholder EDA with trace gas
She Wei is working with Christian on something
Jerome working on perturbation schemes
SOCA - Travis
- Kriti has been adding insitu T/S QC filters into skylab. After 1 or 2 more sprint cycles we should be close to a feature set that should be "good enough" for EMC operations
- Doruk: potential=>insitu variable changes have been added to VADER pending PR approval. We will be adding the linear variable change in the near future
- I have been working on a small-scale correlation operator using an iterative gaussian kernel filter. This will be useful in the ocean at high latitude where the correlation lengths are very small and BUMP struggles. This code is SOCA specific for now, but after the atlas mesh connectivity is implemented, I'll try to find time to generalize this into SABER
