Quality Control of Partner Data
METEO-Cert: acceptance procedure for weather stations
• In 2006 MeteoSwiss started integrating partner stations into their
network to increase the coverage of meteorological surface
observations and to reduce costs.
• To address concerns about the quality METEO-Cert was
developed and applied to both partner and MeteoSwiss’ stations.
• Goals of METEO-Cert are:
1. Quality label for weather stations
2. Comparability between weather stations
3. Systematic acquisition of metadata
WIGOS 2040 Workshop, Joël Fisler
28
METEO-Cert: Quality Labels
Fully compliant
All WMO/CIMO requirements fulfilled
Compliant
Most requirements fulfilled
Not compliant or Special Site
Some important WMO requirements not fulfilled! Be
aware of the limitations and use data with caution.
WIGOS 2040 Workshop, Joël Fisler
29
METEO-Cert: Method & Procedure
• Three steps:
1. Pre-Assessment
2. Audit on site
3. Data analysis
• Audits on site are conducted by a neutral third-party organization
and not by the operator or the NMHS.
• In Switzerland the audits conducted by METAS, the Swiss Institute
for Metrology.  ensures neutrality when assessing stations!

Methods: Criteria
METEO-Cert does take into account 100 criteria per station summarized
in the following categories:
1.
2.
3.
4.
Instrument: Accuracy, Heating, Ventilation
Siting and Exposure: CIMO Siting Class, Measurement Height, …
Maintenance and Observer: Maintenance and Calibration Cycles
Post-Analysis: Data Availability and Timeliness

METEO-Cert: Conclusions
• Deficiencies became visible and improvements were made
to around 10% of the stations.
• Operators became more sensible to quality issues
• Provides information about how the data can be applied.
• Could be adapted for other weather services if required.
 IOM report about METEO-Cert is planned for late 2016. Will
be available on WMO-Website.

Vision for 2040 & Discussion
•
•
•
•
•
Not only sharing data with partners but also planning and building
measurement networks together (optimize the available resources)
Complete metadata information (e.g. in OSCAR) in order to be able to define
possible applications for each measurement network (fit for purpose).
Closer collaboration between governmental organization concerning storing,
analyzing and visualizing environmental data (federal data warehouses)
Open data access for environmental data (worldwide)
Crowd Sourcing (e.g. Weather Underground with worldwide 200’000 stations)
