- Improving robustness of interpolators for the structured grids used in SABER
ALGO:
HTLM Christian:
- Maryam and Christian have been testing the HTLM a good bit and are seeing consistent and significant reductions in linearization error with even with relatively low ensemble sizes. The performance is extremely similar with ensemble sizes of 30 and 15 for example. In some cases we even see some additional reductions in linearization error for variables we aren't updating. These results will also be presented at the Adjoint workshop next week.
- Adding in new configuration options to the HTLM , specifically the ability to read in only the ensemble states at update times while still using a full nonlinear model for the nonlinear control component. This could allow the reuse of a single ensemble for multiple outer loops , or if the ensemble is large the use of a different subset of an ensemble at each outer loop.
Model naming convention Steve V:
- Discussing imposing metadata on model variables and checking for variables to be in the model naming convention for model variables
GEOS Clementine:
- Together with INFRA and GMAO: good progress towards running GEOS-jedi with spack-stack
B matrix:
- Nate: finalized changes to B training suite and looking into use of spectral covariances
- Several optimizations to BUMP from Benjamin Menetrier
Snow DA:
- Tested explicit diffusion operator for snow DA covariances.
- work with infra and NASA on speck-stack
- Discussed model name convention with different agencies regarding using CCPP convention and metdata
- Working on background error covariance training suite. Will also look at spectral data
- BUMP PRs will speed up a few things (e.g. reading global files)
- Ran snow 4D-Var. BUMP has a branch to fix most of the issues (this is related to some of the high-reso issues)
- MetOffice is working on option for hybrid BE in parallel Added diffusion operator for snow into SABER (work from Travis)
INFRA:
Working with ALGO on JEDI-GEOS interface and on updating FV3 dycore and FMS for JEDI-UFS interface
spack-stack
IODA (Note: I gave the update here but actually Anna should have updated on ioda)
Data ingest and EWOK
CI:
Added rttov, oasim, and ropp-ufo to CI tests
Faster churn on features is leading to instability, report breakages on jedi-infra-support or as an issue.
Coming up: CI will be disabled for several hours for an internal migration, this will be announced ahead of time.
