- Opening and approval of agenda
- Secretariat updates
- Review of GRIB proposals
- Review of BUFR proposals
- Review of Common Code Tables proposals
- Schedule of FT2021-2
- AOB
- The library will publish a new version of the MoC vI.2 by mid-June with all of the amendments from FT2020-2 and FT2021-1.
- FT-2021-2
- The amendment documents will still be a subset of the entire manual, but I will have an complete document (almost) to use as a reference until they are published.
- Normalisation of notes in manual and Github
- All GRIB2 notes from the PDF manual and the Github project for GRIB2 templates live in one document and the template CSVs have new columns to reference note identifiers, code tables, and flag tables were updated.
- e.g. notes/templateNotes.csv and product definition template 4.40.
- Issues for tracking discussions and status
- Community website updates
- New information on: https://community.wmo.int/amendment-processes-wis-manuals-and-guides
- Working on consolidating all relevant information at: https://community.wmo.int/volume-i2
- I need volunteers to help review the following pages for relevance and determination of status - The team members suggested getting perspectives from regional reps.
- MTDCF homepage: https://community.wmo.int/activity-areas/wmo-codes/mtdcf
- TDCF Guidance: https://community.wmo.int/activity-areas/wmo-codes/guidance
- Discuss options for removing the 'status' column in the tables
- last meeting ==> ACTION: let us know if your centres are using 'experimental' or if you have ideas about status management.
- options: A) remove status column and keep information in notes; B) change status to indicate deprecation only; or C) Do nothing - The team prefers option B and it is noted that there will need to be a review of the validity the status with values of deprecated.
- issues for tracking status/discussion
Team will review following proposals.
