Agenda/Notes

• Welcome, adoption of minutes (5', jkl)
  • FT2022-1 recently approved by P INFCOM
• Review issues for FT2022-2

In validation

1. Issue 278 - 1-06-02 New code list "Matrix"
   • Discussion (GC) Notation: uppercase and lowercase sensitive? (Joerg) some guide for the notation is available.
   • decision: move to Validated
2. Issue 364 - 1-01-01 Definition of present and past weather variables
   • Action: Proposal approved, summary to be updated to reflect sources considered.

In discussion

1. Issue 142 - New table 5-02-03: Measurement/observing method (ocean)
   • To be discussed next time
2. Issue 281 - 5-02-05 Methods for Terrestrial domain - new terms for hydrology
   • Discussion: (Joerg) length of description to be cut off
   • Action: Juan to update the branch; Johanna to review the branch for consistency check
   • Decision: move to "In validation"
3. Issue 295 - 1-01-05 new entries and revision for hydrology domain
   • Action: Johanna to review the branch for consistency check
   • Decision: move to "In validation"
4. Issue 336 - Table 5-02-01: new methods of observation (for atmospheric variables)
   • To be discussed next time
   • Action: Joerg to review the isssue
5. Issue 339 - Create new table: time zones
   • Discussion: (Joerg) Any criteria for the description? The shorter description is always good. (Anna) to be complete is good. (Juan) I used the python TZ database.
   • decision: keep the description as it is now.
   • Decision: move to "In validation"
   • Action: Juan to update the summary of the proposal about the reference
6. Issue 365 - 1-02 Measurement Unit: Improve definition of year
   • Decision: to use "conventional unit of time" (365 or 366 days) and to keep the notation
   • Decision: to move to "In validation"
   • Action: Franziska to create the branch; Joerg to review
7. Issue 381 - Request for qualifier to be added: Relative Humidity (%)
   • Decision: to supersede "Humidity" and add "Relative Humidity" (with respect to water)
   • Decision: to open new issues to address 'mass mixing ratio' and clean up of other humidity related codes (this should be associated with the gap analysis)
8. Issue 387 - Proposal for an observed variable, http://codes.wmo.int/wmdr/ObservedVariableAtmosphere #215
   • Decision: observations of precipitation from the fog
   • Action: John to verify with Salome
   • Action: Anna to tag Salome about the proposal and notify her that we will not add a new variable but the method
9. Issue 388 - Proposal for an observing method, http://codes.who.int/wmdr/ObservingMethodAtmosphere
   • Discussion: the team agrees with the name of the method: Fog collection

Submitted/New

1. Issue 389 - 1-01-01 Align radiation variables with OSCAR/Requirements and add definitions
   • to discuss next time
2. Issue 390 - Addition of variable definitions (part 1: clouds)
   • to discuss next time
3. Issue 391 - 1-01-01 Addition of variable definitions (part 2: lightning)
   • to discuss next time

• AoB
  • Joerg made a brief introduction about the OGC general assembly in Madrid in mid-June. He will give a presentation about the new cases for WIGOS metadata, new standards, and the observation measurement.
