General announcements

  • Next meeting in two weeks (no special topic for next week's time slot)
  • Send in any special topics you are interested in presenting and discussing

Infra - Evan

  • Ashley added a new ingest suite for ERA5 Analysis
  • Evan and others are looking into doing EWOK tasks in a Singularity container
  • Good progress with test and installation automation for R2D2 (Eric, SteveG)

Interfaces - Liam

  • Raji submitted two PRs
    • C++ implementation of surface pressure operator using the UKMO and GSL schemes
    • Updates to filters for better traceability using the oops::Log::trace() channel
  • SteveH and SteveV are working on the new IODA reader refactoring and integration of the new ObsSpace DataFrame
    • New reader steps: Load (file I/O), Filter, Distribute
    • Filter step implementation is done, Load (SteveH) and Distribute (SteveV) steps are work in progress
  • Met Office contributed a IODA parallel ODB reader (in develop)
  • NOAA-EMC contributed a IODA parallel BUFR reader (PR under review)
  • Many thanks to our partners for these valuable contributions
  • Liam is continuing work on GPU offloading in Atlas, Ectrans for various steps including adjoint, inverse, etc.

Algo - Clementine

  • Christian is back from PTO and is working on the continuous DA capability
  • Nate is adding a feature for writing out lat, lon files from any model which will be used to compute scores
  • Clementine
    • Adding capability to compute scores using WeatherBench
    • Assisted with work to run EWOK tasks in a Singularity container
    • Cleaning up the EWOK repo, including removing obsolete code

COMPO - Jerome

  • PRs submitted for ingest of new aerosol obs types

Marine - Kriti

  • Work in progress with 4DVar, HTLM

OBS - BenR

CRTM - Cheng

  • CRTM V3.2, final check for all instrument coefficients in netCDF format.
  • New coefficients generation for PACE
  • Bug fix:
    • azimuthal-dependent calculation for CRTM Jacobians (visible channels)
    • surface emissivity Jacobians (UFO QC tests)

NOAA-EMC - Dan

  • Focus is on testing and qualifying flows including ones that use JEDI
    • Realtime runs
    • Reproducibility checks
      • Good results in general
      • Some obs types are showing poor results and are being investigated
        • H(x) differences of 10's of Kelvin, has some dependency on the number of MPI tasks being used
      • Plan moving forward is to dump out quantities in single precision and call it good when differences are within roundoff errors
    • Qualification with entire workflows in underway
  • Cleaning up the build processes including eliminating forked repos (eg, MOM6)
  • Moved to spack-stack-1.9.1
    • Ron's parallel BUFR reader PR has been waiting for spack-stack-1.9.1 and is now ready for review

GMAO - Ricado

  • Checking GSIBEC results and will keep EMC updated
  • Finishing up work with Francois H. to implement interpolator changes needed by GSIBEC
  • Wrapping up fixes for CO2 UFO operator issues
  • Put knobs into GMAO workflow for cycling DA
  • Seeing good results with SWELL
  • Starting to look into ingesting SABER(?) obs into JEDI
    • Measurements from mesosphere, upper stratosphere
    • Have a converter to BUFR, working on path to ingest in JEDI

MMM - ChrisS

  • Developing/updating reference configs for workflows
  • Prep for MPAS-JEDI tutorial scheduled for this June in Scotland
  • Updated obs2ioda converter to directly output IODA V3 format
  • Working on hourly cycling in DA flows

Met Office - MikeC

  • We don't have any updates from the UKMO this week which were not part of the quarterly review.
    • We have had bank holidays over the easter period. 
  • In terms of general work:

    • We continue to implement JEDI operationally for the observation processing and the trialing looks good

      • This is planned for operational implementation at the end of 2025  

    • We are currently testing working on HTLM, hybrid-B, multi resolution testing in preparation for our next generation HPC benchmarking exercise

      • Due later in 2025

OAR - no update

ROMS - HernanA

  • Qualifying more realistic 4DVar flows
    • Error analysis
    • Looking at innovation, increments, background variance, etc.
    • Working out tuning and calibration for the flows

NRL - no update


  • No labels
