- From Nate:
- Finalized plan for initial prototype of diffusion-based correlated R (with Kriti)
- Spinning up on Space Weather project, Need to add IODA and UFO as dependencies to PyIRI-JEDI, and update PyIRI-JEDI CI with this change
- Finishing up hand-off of multi-scale B
- From Christian:
- PR for sliding window continuous DA is ready
- Beginning to add workflow in ewok to enable larger scale testing with with continuous DA
- Removed parameters from the HTLM
- Will begin adding some adaptive regularization to the HTLM
OBS OBS (Benjamin Ruston):
- IODA converter:
Draft PR from Raji, this build on the work contributed by MMM, and re-aligns the NCAR obs2ioda converter adding a c++ layer and some bugfixes. Raji converted the make structure to match the convention used in JEDI, and removed dependency on an external yaml parser. https://github.com/JCSDA-internal/ioda-converters/pull/1695 - UFO:
- Replacing the SfcPcorrected with, SfcCorrected operator (UFO https://github.com/JCSDA-internal/ufo/pull/3779). Please be aware, if you are using SfcPCorrected you would shift to this more general operator.
- Reconstructed radiance PR for RTTOV https://github.com/JCSDA-internal/ufo/pull/3754, this allows for use of hyperspectral radiance reconstructed from PCs. An equivalent effort for CRTM by Bryan K. is underway, meeting with Stefano and Mike Cooke occurred and moving along nicely.
- NASA GMAO R. Todling, JCSDA, and NOAA EMC met to discuss the implementation of NBAM operator for dual use in the NOAA and NASA systems. https://github.com/JCSDA-internal/ufo/pull/3778

CRTM (Ben Johnson)
EMC noted an issue that under very rare circumstances, a negative radiance or inf/nan could be produced in CRTM. It was noted that this occurs when graupel is present in the model data, and when using the GFDL CloudCoeff file in CRTM, and only occurs at 166 GHz (possibly higher).
The root cause appears to be the truncation factors for delta fit are not normalized. See issue https://github.com/JCSDA/CRTMv3/issues/241
A fix was provided to EMC which addressed the short term issue, but CRTM team will work on correcting the table and providing a comprehensive assessment of all of the cloud LUTs provided by PSU to ensure this problem does not occur in other tables.
GMAO GMAO (Ricardo Todling):
- Continue JEDI tests. Unfortunately, some tests doesn't generate reasonable results as they did in the past runs, e.g., skin temperature for IR
- Also tackled FV3 side issues passing pressure to NBAM operator. Now surface pressure is reasonable. Also wondered about the adjoint tests of this operator. Can't find adjoint tests for UFO operators (- Hernan recommended to perform single obs test). Also super-refrectivity QC doesn't generate the GMAO flavored results.
