Item
1st Session of the Task Team on WIGOS Data Quality Monitoring System
(13-15 December 2016, Geneva, Switzerland)
WIGOS PO, 11 January 2017

2. Objectives of TT-WDQMS-1
i) Review the terms of reference of TT-WDQMS ii) Review the WDQMS concept and its main functions iii) Review the WDQMS pilot project with NWP centres iv) Assess the results of the WDQMS demonstration project in RA I v) Update/further elaborate the WDQMS concept and its main functions, including the relation to the Regional WIGOS Centres vi) Discuss approaches to extend the WDQMS to all components of the GOS, as well as to integrate all WIGOS observing components in the system vii) Draft the work programme/action plan of TT-WDQMS

3. Major Outcomes of TT-WDQMS-1 (1)
i) It recognized the need to make the WDQMS interoperable with OSCAR/Surface, but agreed that they are two different systems:
- Interoperable meaning that essential information should flow between them to ensure consistency, e.g. both systems should see the same stations
ii) Integration of non-GOS observing systems into WDQMS does not mean replacing the existing monitoring systems, e.g. those existing in GAW, rather to make them all working under the same overarching system concept.
iii) Agreed to introduce the notion of Global WIGOS Centres (GWC) into the structure of WDQMS, additionally to the notion Regional WIGOS Centres:
- GWC should maintain a global portal for the monitoring of specific observing system, and be a reference for the activities of RWCs, e.g. running the global monitoring tool(s).
iv) The Monitoring pilot project developed in cooperation with the Global NWP Centres, achieved lots of progress:
- monitoring output files agreed in terms of content and format, and made operationally available by ECMWF, JMA and NCEP (recently also DWD, MSC in future)
- benefits of bringing together the activities of various NWP centres, enables to identify and understand the differences amongst them regarding the monitoring results

4. Major Outcomes of TT-WDQMS-1 (2)
v) “Business rules” on how to aggregate the monitoring results (Evaluation Function) to be made available to Members, need further development
vi) WDQMS global web-tool takes the monitoring files from NWP centres to show 6hourly maps: runs by itself, available at
vii) The Incident Management function running at RWCs will not replace any existing national IMS - results from RWCs should be taken for action by NMHS
ix) The assessment of results from the WDQMS demonstration project in RA I:
- beneficial for both the consolidation of the WDQMS system, and also for the participating Members due to identification of issues of which they had previously not been aware, most of them related to incomplete or incorrect metadata in OSCAR/Surf.
- there is a need for more training
- the demonstration project didn’t have enough duration to cover all the expected types of quality issues for both surface and upper-air observations
- Future RWCs should work on a consolidated list of stations to be monitored
- The issue of persistent incidents was recognized as something the system has to deal with – the approach of creating a “log of known issues” was suggested.

5. Major Outcomes of TT-WDQMS-1 (3)
x) Need for WDQMS NFP was recognized, for nomination by PRs; ToR needed
xi) Guidance document on WDQMS for RWCs, drafted by T.Kleinert & S.Klink, is applicable to the GOS stations - EUMETNET has been a major contributor!
xii) The following order of the systems to be included in the next development steps of WDQMS Demonstrations/Pilot Projects is proposed:
- finish the work on Land Surface Pressure observations (GOS) and include timeliness of observations in the reporting;
- extend what is already in place for Kenya and Tanzania (RA I demonstration project) to include the radiosonde observations;
- GOS Ocean observations of surface pressure and sea surface temperature;
- GOS aircraft observations of temperature, wind and humidity;
- CLIMAT messages from GSN & RBCN.
xiii) Clarification is needed regarding the meaning of (f) of WDQMS roadmap in the PWPP: Mechanisms for routine reporting of monitoring results to EC, regional associations and Members by end of 2017.

6. Major Outcomes of TT-WDQMS-1 (4a)
viii) A set of graphical representations of the WDQMS were developed, starting with simple schemas that can be more and more detailed (Figs this and next slide)
