First Session of the ICG-WIGOS Task Team on WIGOS Data Quality
Monitoring System
The First Session of the ICG-WIGOS Task Team on WIGOS Data Quality Monitoring System
(TT-WDQMS) was held from 13 to 15 December 2016 at Geneva, Switzerland. This Task Team
is a formalization of the ad-hoc activities by a group of experts, following the outcomes of two
WIGOS Workshops on Quality Monitoring and Incident Management held on December 2014
and December 2015.
The TT-WDQMS-1 had the following objectives according to the agenda:
i) Review of the terms of reference of TT-WDQMS
ii) Review of 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
4.3.6.1
Major Outcomes from TT-WDQMS-1
i) The TT-WDQMS recognized the need to make the WDQMS interoperable with
OSCAR/Surface, but agreed that they are two different systems. Being interoperable meaning
that essential information should flow between them to ensure consistency, e.g. both systems
should see the same stations.
ii) The integration of other non-GOS observing systems into the WDQMS does not mean
replacing the existing monitoring systems, such as those of the GAW, rather to make them all
working under the same overarching system concept.
iii) TT-WDQMS agreed to introduce the notion of Global WIGOS Centres (GWC) into the
structure of the system, additionally to the existing and already approved concept of Regional
WIGOS Centres (RWC). A GWC should maintain a global portal for the monitoring of a specific
observing system, and it should be a reference for the monitoring activities of various RWCs,
e.g. running the global monitoring tool(s) for the land surface stations of the GOS.
iv) From the Monitoring pilot project developed in cooperation with the Global NWP Centres, a
lot of progress was achieved, namely the monitoring output files agreed in terms of content
and format, and they have been made operationally available by ECMWF, JMA and NCEP
(recently DWD joined the project and MSC is also interested in joining). The pilot project
allowed recognizing the benefits of bringing together the activities of various NWP centres,
which enables to identify and understand the differences amongst them regarding the
monitoring results.
v) The “business rules” on how to aggregate the monitoring results, at the Evaluation Function
of WDQMS, to be made available to Members, were discussed but further development is
needed.
vi) The WDQMS global web-tool developed at WIGOS-PO takes the monitoring files from NWP
centres to show the 6 hourly results on geographical maps; it runs by itself and is available
online at http://128.65.196.37/wdqms/.
ICG-WIGOS-6/Doc. 4.3.7, p. 3
vii) It was agreed that the Incident Management function running at the RWC are not intended
to replace any existing national Incident Management Systems (IMS), but the results produced
by the RWCs (i.e. incident tickets and procedures) should be provided to the NMHSs for their
further action.
viii) A set of graphical representations of the WDQMS were developed, starting with simple
schemas that can be more and more detailed (Fig.1 a, b, c, d, e).

ix) The results from the WDQMS demonstration project in RA I, were assessed based on the
national reports by the participating Members (Kenya and Tanzania). The conclusion was that
it was beneficial both for the consolidation of the WDQMS system, as well as 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 described in OSCAR/Surface.
The need for more training was recognized. The demonstration project itself was deemed not
have been of long enough duration to cover all the expected types of quality issues for both
surface and upper-air observations. The future RWC 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.
x) The need for WDQMS-specific National Focal Points was recognized, to be nominated by
Members. The ToRs are to be developed.
xi) The guidance document on WDQMS for RWCs, which was drafted by EUMETNET (Tanja
Kleinert and Stefan Klink), is applicable to the stations of the GOS. The session was briefed on
the plans for a RA VI project “RWC in a nutshell”.
xii) The TT-WDQMS-1 proposed the following order of the systems to be included in the next
development steps of WDQMS Demonstrations/Pilot Projects: Finish the work on Land Surface
Pressure observations (GOS) and include timeliness of observations in the reporting; extension
of 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 item (f) of the roadmap for WDQMS in the
Plan for the WIGOS Pre-operational Phase: Mechanisms for routine reporting of monitoring
results to EC, regional associations and Members by end of 2017.
