Agenda

• Welcome [jkl, 5’]
• Acceptance of minutes [jkl, 2’]
• Secretariat Updates [am, 5’]
• Review FT22-1 proposals

Notes

Proposals

Valid (ready for FT22-1)

1. table 1-01-05: replace Permafrost with three new variables
   • Validated
2. Table 1-02: New measurement unit "metres per year"
   • Validated
3. Table 1-02: Add missing unit to supersede mg_m-3_25C
   • Validated
4. Table 1-01-01 radionuclide codes
   • Validated
   • Discussion
     • Joerg: DWD expert is recommended for comments, Stakeholders: to have formal representation from CTBT, the procedure to get involved other experts is still not so clear
5. 1-01-01 addition of greenhouse gas variables from WDCGG
   • Validated

In Validation

1. 1-06-01 New code list "Domain"

   • Discussion
     • Joerg: we are waiting for feedback from GOOS.
     • Meulen: IOC should be reached as a stakeholder; (Enrico: we have an IOC contact)
     • John: Compared with domains that are separated in OSCAR/RRR, the definition is of more importance and needs improvement.
     • The team agrees to park it and finalize it in the next FT, and to expand the definition to address saline lakes in the hydrological category.

2. 5-02-01 Lidar in Measurement/Observing Method (atmosphere)

   • Discussion
     • The team agree to replace the observation by measurement, and also to "keep particle phase".
     • Gao points out the comments from ET-UAM (Upper-air Measurement) didn't really understand and focus a lot of the CURRENT rows, not the NEW ones (to be proposed to replace the CURRENT rows). Gao will review the table changes from ET-UAM and come back with a report including what is to be accepted or rejected.
     • John mentions that it should be consistent with the observation layer.
     • Meulen provides the information about the list of ET-UAM members who responded to the review. The team agrees that Secretariat will coordinate with this team to thank their contribution and to discuss the changes they proposed.

3. 2-02 programs additions and updates

   • Discussion
     • OceanOPS team provides the feedback ASAP, no later than early January.

4. 1-01-01 addition of new atmospheric variable (lidar, ceilometer)

   • Not Discussed

In Progress

NOT DISCUSSED

1. New table 5-02-03: Measurement/observing method (ocean)
2. 1-01-x Re-concile variable lists of OSCAR/Requirements with the official WMD codelists
3. 1-01-01 additional variables (mostly originating from EBAS)
4. 1-06-02 New code list "Matrix"
5. 1-01-05 new entries and revision for hydrology domain
6. Create new table: time zones
7. Table 5-02-01: new methods of observation (for atmospheric variables)
8. 5-02-05 Methods for Terrestrial domain - new terms for hydrology

Submitted

NOT DISCUSSED

1. 2-02 Programs/Joerg: to add more details into Consultations Add name and affiliation/networks: addition of space component
2. New table 5-02-04: Measurement/observing method (outer space)
3. New table 5-02-02: Measurement/observing method (earth)
4. 1-01-01 Atmospheric variables
5. 6-01-02 Creation of a new code table RelativeHumidity
6. 1-02: Align plurality of units with SI conventions
7. 1-02 Measurement Unit: Improve definition of year

Actions

• 1-01-01 addition of greenhouse gas variables from WDCGG
  • Joerg: to add more details (name, contact information) into Consultations
• 1-06-01 New code list "Domain"
  • Anna/Enrico: to reach out the IOC colleague for review
• 5-02-01 Lidar in Measurement/Observing Method (atmosphere)
  • Gao: to review the feedback from ET-UAM(Expert Team on Upper-air Measurement）and provide a report including what changes to be accepted and rejected.
  • Anna: to coordinate with ET-UAM when the report from Gao is ready
• 2-02 programs additions and updates
  • Magali: to review and provide comments as soon as possible, no later than 4 January
