2nd Joint meeting between TT-WISMon and TT-WDQMS-2022-Jan-21

1

Opening

Timo

Timo:Data Policy, GBON were approved. To build the pilot project for WIS2.0 monitoring.

Timeline for monitoring GBON implementation was set in the summer.

Objective tool: look at data at different points, not to be linked to NWPC

Cristina: What is the idea behind GBON?

Enrico: 1) GBON was approved in Cg-2021; 2) to build a team for GBON implementation; 3) not clear for the stations selection creteria; 4) Monitoring of both WDQMS and WIS, the objective this joint team

High-level architecture

Presentation

Timo

Presentation is here. The goal is to leverage the principles for monitoring.

Questions to be discussed:

1. Exchange format

2. Link between distributed sensor-centers and central storage/reporting component

Discussion

ALL

Kai

• Shares the presentation of WIS2.0 Monitoring Procedures.

  • Sensor Centers (requirements, procedure,)

  • Monitoring Centers

Enrico

• It is a good starting point.

• to provide the software to the centers (opensource)

• GTS: multiple stations in one message

• WIS2.0: to avoid having collective messages

• Complexity of monitoring lies in decoding part (many BUFR templates), for example, 5+ templates for SYNOP

Timo: we need pragmatic ways

• broker: sensor centers to have one broker each or a cloud based broker

• 2 or 3 sensor centers (to standardize the message format)

Jeff

• US: support this proposal, not for GISC Washington

Enrico

• to make a decision about the proposal today

• to reach TT-GISC for their contribution

• a strategy of data sent in real time

Kai:

• preference: active

• WIS2

Cristina

• preference: active (if software provided)

Cristiano

• preference: active

• guidance needed for sub-pub in real-time

• process for WIS pilot project

  • Timo: ECMWF and WMO MoU for software development, and it is also a member driven process

  • Enrico: to think 5 sensor centers generating traffic, a real-time data, monitoring near-real-time is acceptable; some tests are needed

  • Kai: amount and frequency of reports: no impact on technical implementation; message received, reports to be grouped on an hourly basis and sent out

  • Enrico: MQP, group the report of messages.

  • Timo: to discuss the configuration variable of aggregation rules at the next meeting

  • JMA would be also a sensor center.

  • Hassane: 1) real time is more useful at the local level not the global level; 2) determinator: compare what we receive and what it is expected to receive; 3) component in WIS2node
