1 Review WIS2 Pilot Phase Plan, check progress

Hassan updated on the progress of wis2 pilot phase.

For Cg-19, side-event to be confirmed. We applied some devices for the booth at Cg.

Task Team on NWPMD

• Q1:Whether data other than core data can be cached by GC? (mandatory GDPFS products are not defined as core data now)

(Baudouin) Caching is different from Data Policy.

(Remy) refer to the issue on GitHub - Prevent caching of large datasets in Global Cache (https://github.com/wmo-im/wis2-guide/issues/7

• Q2: Can NWP centers bundle core data and other data?

Q3: Mechanism of notification for a new version of data file

(Remy) if a data is to be updated,

(Weiqing) in GTS, header remains the same, message with correction.

(Baudouin) GTS way is not a bad one with correction

(Kenji)

Action: Hassan to create an issue on repository on message notification mechanism on updated data.

Q4: Can part of big file be extracted using API prepared by Global Services.

(Remy) Such potential API requests should not be covered by Global Services.

(Baudouin) will API be covered in the next version of WIS system?

Q5: Is there a way to filter certain kinds of products under a particular topic using global broker subscription?

(Remy)

(Anna)

(Baudouin) In NWP, e.g., for each leap time, there is one file, including all the parameters.

(Jeremy) discovery metadata

2. wis2box update

Enrico

We are working on a number of issues. After training, we discover some issues. Synoptic is working on UI design.

3. Prioritise and review open GitHub issues

Jeremy

https://github.com/wmo-im/wis2pilot/issues open issues but without update.

(Jeremy) Propose to add wis2 pilot phase on the WIS community platform activity area.

(Remy) WIS to GTS Gateway & GTS to WIS Gateway is still not clear. Indonesia request to play GB replacing Australia is not updated.
Morocco (Global Monitoring)

(Hassan) To collect the questions and progress of each issue from the participants, either by updating GitHub repository (Jeremy) or a compiled PDF (Remy).

(Remy) end of June, Cache is available from USA.

(Weiqing) We are still working on Global Cache. For Global Broker, our decision remains the same. We could also do Global Broker if it is insisted.

Decision: It would be better that Australia works as a Global Broker instead of Global Cache considering there are four players for GC.

Action: Hassan to help coordinate about the general GC issues.

Update on each WP1-11

Action: Hassan to compile the progress on wis2nodes.

(Timo)

• WP9-ICAO/SWIM interface

(Hassan) We plan to establish a task team (expert team?) (most of them are from ICAO) and we propose to choose from TT-AvData as the candidates as some of new TT members are from Met Office.
