Minutes (predicted)

Review previous actions

  • DONE - Anna: help organize GitHub issues alignment with FT branches
  • DONE - Anna: follow up on email options for public consultation
  • IN PROGRESS - ALL: Choose a branch to validate, self assign in issues and capture notes in issues.
  • IN PROGRESS - Jan, Choy and interested: To finalize the issues involving WC and WV SIGMET within this week
  • IN PROGRESS - Choy: To finalize changes with regard to the code lists and prepare the corresponding RDF files for evaluation

IWXXM 2021-2-dev draft

  • Confirm the distribution is fit-for-public consultation and identify outstanding items (https://github.com/wmo-im/iwxxm/labels/publicConsultation)
    • Individual package
      • METAR/SPECI: OK with resolvable outstanding item
        • Outstanding item: Improve descriptions in iwxxm:runwayState
      • TAF: OK with resolvable outstanding item
        • Outstanding item: Re-version as 3.0.1
      • SIGMET: Not OK with regard to changes to schemas and examples to fix #209. Participants were of the view that while Note 19 did mention "Each location and forecast position is to be preceded by an observed or forecast time", it was not until the publication of examples in the ICAO APAC SIGMET guide that the first observation time could be different for tropical cyclone position + first CB cloud and the second CB cloud. This was beyond the normal understanding of providing "snapshots" in messages and will affect the information model of IWXXM SIGMET. In the worst case we may need to separate WS, WA and WC SIGMETs into 3 different information models instead of sharing a single core part. The team agreed that we shall mark it as a known issue and bring our concern back to the respective ICAO team (which should be WG-MOG) for their attention. See also Note 1 at the end for additional information on our views with regard to information requirements.

Meeting ended at 2021-April-30 10:15UTC. To be resumed at 2021-May-3 10:00UTC.
