COSIMA TWG Meeting Minutes 2023

Meeting Minutes

Date: December 7, 2023

Attendees:

Changes in Meeting Format:

  • First monthly meeting dedicated to updates from TWG.
  • Second monthly meeting focused on discussing issues, planning, and prioritizing work.

Ezhil:

  • Developed the IAF Configuration for MOM6-CICE6-WW3.
  • Compared MOM6-CICE6-WW3 IAF data with NDBC buoy data; good match for lower HS, deviation for larger HS.
  • Resolved a bug in existing MOM6-CICE6 IAF configuration; year_align in IAF should match year_start in streams XML.

Discussion on year_align for RYF Configuration:

  • Correct year_align crucial to avoid incorrect forcing.
  • Debate on ideal year_align for RYF: use 1900 (start of RYF dataset) or 0000 (simulation start year).

Dougie:

  • Completed first successful om3 run with bling, focusing on CO2 and O2 concentrations.
  • Addressed handling of fields not provided by the atmosphere.
  • Discussed reading capabilities for files not provided by model components.

Anton:

  • Identified a bug in openmp hindering parallel reading.
  • Working on adding chunking info to CICE output.
  • Progressing with CICE standalone on Gadi; exploring different CICE versions and potential CICE6-WW3 integration using NUOPC.

Michael:

  • Discussed git workflow for patch file creation and PRs; emphasized unified repo and configuration branching.
  • Collaborating on name list file comparison between configurations.
  • Covered profiling challenges, work with cmake, and Python scripts for configuration management.
  • Raised questions on the applicability of optimization tools across different models.

Harshula:

Two-Week Planning:

  • Ezhil: Continue development and analysis in IAF configurations, comparison with satellite data and seek BOM assistance to check the flags and input parameters of ww3.
  • Anton: Finalize CICE standalone; collaborate on analysis recipes.
  • Dougie: Assess output from coupled bling runs; seek NCAR MOM assistance.
  • Michael: Prioritize optimization and profiling for an OM3 configuration.

Next Meeting:

  • Scheduled for December 20, 2023, to discuss further planning.
