Agenda & Notes

• Welcome, adoption of minutes (5', jkl)
• Secretariat updates
  • Fast-track 2022-1 amendments were adopted by the P/WMO yesterday, next step: publish to codes registry
    • Action: Anna to set up a meeting for further discussion
  • OSCAR/Space metadata templates and space-related parameters
    • Heikki from Secretariat/Space Systems and Utilization Division is creating WIGOS metadata records for satellite data which can be produced from OSCAR/Satellite. Space-related vocabulary terms. (building templates). Heikki has been invited to GitHub working space to collaborate with experts. John Eyre is happy to work with Heikki. Two strategies:1 produce a valid satellite template; 2. a list of parameters to be mapped from OSCAR-space to Codes registry.
    • Action: Joerg and John will join Heikki for the development of OSCAR/space metadata templates
    • Action: Anna to open an issue to keep track of the progress
  • Status of introducing KPIs and metadata evolution to INFCOM
    • Action: Joerg to contact Rémy(SC-IMT Chair) and Tom (ET-Metadata, Chair)
  • Issue management details
    • https://github.com/wmo-im/wmds/projects
    • Branch, add the issue ID in the comment, having a link the branch and the issue together
• Review issues for FT2022-2

FT2022-2 issues

In validation

1. 1-01-01 Definition of present and past weather variables #364
   • Action: Joerg to review it
2. 1-01-05 new entries and revision for hydrology domain #295
   • Juan: to remove the ()
   • Anna: is it good to refer to a publication in a definition for the term?
   • Joerg: gravimetric method is the term used in hydrology.
   • Gao: to use "based on"
   • John: state both names "Based on the term used in ..."
   • Action: Anna to prepare a template for best practice (to propose some suggestions on different types of references)
   • Action: Juan to update the branch and Joerg to review it
3. 5-02-05 Methods for Terrestrial domain - new terms for hydrology #281
   • Action: Juan to update the branch and Johannes to check the consistency
4. Request for qualifier to be added: Relative Humidity (%) #381
   • Markus: Metrologists now recommend using "amount fraction" instead of "mole fraction".
   • Decision: to change from "mole fraction" to "amount fraction" (mole is more about the unit, not dimension)
   • Action: Anna to update the branch
5. Create new table: time zones #339
   • Action: Anna to update the table number
6. 1-02 Measurement unit addition #396 (new, but simple)
   • Action: Joerg to update the proposal summary and Anna to update the branch
7. Add 'fog collection' to table 5-02-01 #388
   • Agreed on what discussed at the last meeting

In discussion

1. Add variable for fog to table 1-01-01 #387
   • Action: Joerg to add comments to summarize the current proposal: 'precipitation from fog' to be expressed as 'amount of precipitation' and the (new) method 'fog collection' Validated - no discussion, just make sure issue summary is complete
2. 1-07-01 New code list "Domain" #277
3. 1-01-01 addition of new variable "relative attenuated backscatter" #367
4. 1-07-02 New code list "Matrix" #278

Ready for FT approval procedure - no discussion needed

1. 2-02 Programme/network affiliation: Supersede ANTON(x) by RBON #385
2. 2-02 Programme/network affiliation: Supersede CLIMAT(x) by RBON #382

Other issues

Submitted

1. Table 5-02-01: Measurement/observing method (atmosphere) - new method for GHG observation #397
   • To move to "in discussion"
   • Action: Joerg and Gao to finalize by COB today, aiming to go for FT2022-2 In discussion

• Decision: to tag for FT2023-1

1. 1-01-01 Align radiation variables with OSCAR/Requirements and add definitions #389
2. 1-01-01 Addition of variable definitions (part 1: clouds) #390
3. 1-01-01 Addition of variable definitions (part 2: lightning) #391
4. New table 5-02-03: Measurement/observing method (ocean) #142
5. Table 5-02-01: new methods of observation (for atmospheric variables) #336
