Agenda

1. Welcome [jkl, 5’]
2. Acceptance of minutes [jkl, 2’]
3. Secretariat Updates [am, 5’]
4. Review FT22-1 proposals
5. KPIs - brief status update if there is time

Notes

• New introductions

  • Magali Krieger introduced herself, she represents the OceanOps community
  • John Eyre with UK MetOffice, previously worked on the OSCAR RRR and is looking at the inconsistencies between WIGOS Codes and OSCAR requirements
  • Itze van der Meulen with KNMI and is member of CIMO group and is looking at the code tables for Methods

• Joerg explained where we are in the Fast-Track procedure for FT2022-1; Many of the proposals on the table will probably be not ready this cycle and will require more discussions and reviews by the broader community. He also mentioned that the governance of the codes will need to be refined. He also explained that the evolution of WMDR will need to be discussed and this will take time. (Laura) Are we being too quick with proposing or accepting changes to the codes and standard? (JKL) the requirements should come first and be well founded. The challenge is identifying stakeholders early on. (Gao) We should have boundary conditions for the solutions (JKL) The challenge is determining the team's role in affirming/validating amendments. (John) Who does this team report to? (Answer) TT-WIGOSMetadata==> ET-Metadata ==> SC-IMT (Anna) .... (Rodica) Suggests revisiting past processes, how it's evolved with reform and how to engage stakeholder; She also stressed that most of the variables in OSCAR don't have methods (JKL) It would be good to have an approach for organizing methods that can happen asynchronously; an adhoc group would be useful (John) Methods are well documented for satellites in OSCAR/Space; (JKL) is this reflected in the WIGOS Codes? (John) there are gaps; there are some challenges with the WIGOS model and it will help to take time. (Jitze) PoCs in RRR are reponsible for application areas; perhaps, identifying PoCs for the WIGOS metadata would help with identifying stakeholders; As an editor on WMO No. 8, there are a lot discussions on harmonization of definitions; In WMO-No. 8, the methods are not really clear. This will take a lot work; (JKL) We need to act and can't take forever to make changes. (Gao) Suggests listening to recommendations and then the team determines the solution.

• The team discussed codes that are 'In validation' phase and are likely to be ready for this FT (see notes in issues below). The team did not discuss other issues.

FT22-1 Proposals

In Validation

1. 1-06-01 New code list "Domain"
2. 5-02-01 Lidar in Measurement/Observing Method (atmosphere)
3. Table 1-02: Add missing unit to supersede mg_m-3_25C
4. table 1-01-05: replace Permafrost with three new variables
5. Table 1-02: New measurement unit "metres per year"

In Progress

1. New table 5-02-03: Measurement/observing method (ocean)
2. 1-01-01 additional variables (mostly originating from EBAS)
3. 1-06-02 New code list "Matrix"
4. 1-01-05 new entries and revision for hydrology domain
5. Create new table: time zones
6. Table 5-02-01: new methods of observation (for atmospheric variables)
7. 5-02-05 Methods for Terrestrial domain - new terms for hydrology

Submitted

1. Table 1-01-01 radionuclide codes
2. New table 5-02-02: Measurement/observing method (earth)
3. 1-01-01 Atmospheric variables

Other Issues

1. 1-01-x Re-concile variable lists of OSCAR/Requirements with the official WMD codelists
   • remove FT2022-1 milestone?(am)
2. 6-01-02 Creation of a new code table RelativeHumidity
3. New table 5-02-04: Measurement/observing method (outer space)
4. 2-02 Programs/networks: addition of space component
