Data or Metadata?
One man’s data
are another man’s metadata
Data and metadata
must hold on to each other!
• Position of aircraft making AMDAR observations
• Surface pressure observation used for GPS IWV inversion
• Total ozone data used to calibrate radio sonde observation

Rationale 1: Discovery and Access
 Numerical weather forecasting
 Aeronautical meteorology
 Disaster risk reduction
 Agriculture
 Climate applications
 Air quality and health
 Sand and dust storms
 Glacier melting and sea level rise
 …
… All need observations, discoverable and accessible

Rationale 2: Interpretation
“The details and history of local
conditions, instruments, operating
procedures, data processing algorithms
and other factors pertinent to
interpreting data (i.e., metadata) should
be documented and treated with the same
care as the data themselves.”
GCOS Monitoring Principle #3, 1999

OSCAR «Recipe»: Ingredients
1. A vision (WIGOS IP)
2. A task team (TT-WMD)
3. An international organization (WMO)
4. A national weather service (MeteoSwiss)
Mix well and let stew to form a
team with common
understanding of scope and
objectives …
5. An ICT partner (European Dynamics)
6. Lots of money
You may need to ask for more
along the way …
7. Time
If you’re short on that one … just
work harder

OSCAR «Recipe»: Instructions
1.
Develop standard for WIGOS
metadata  WMDS
2.
Build Application for registration
and management of metadata
incl. machine-to-machine
interfaces to external metadata
sources
3.
Build a module to translate
observation metadata into
 «Capabilities»
4.
Integrate an (existing) application
to specify and manage
 «Requirements»
5.
Build an application to compare
the two  (Gap) Analysis
6.
Use the results of your analysis
7.
Repeat regularly  RRR

•
Setup of OSCAR environment at MeteoSwiss

Fixed in-situ
•
Fixed in-situ profilers (e.g., radio sondes, aircraft)
•
Ground-based remote-sensing (radars)
model lacking

Metadata management
Presidents of Technical Commissions | 29-31 January 2015, WMO Geneva
J. Klausen, B. Calpini, and project teams
9
Integration of data sources (I)
• Vol A
• Mapping mostly understood
 «synoptic» will be translated into individual observations
 «ObsRemarks» will be partially considered
• Integration of existing database (one-time integration)
• Management by users through UI
• Batch upload as .CSV and .XML files will be supported
• GAWSIS
• Migration of existing database (one-time integration)
• Management by users through UI
• Integration of WOUDC, WDCGG, WDCA, WRDC, EMEP
metadata (weekly)

Integration of data sources (II)
• JCOMMOPS
• Exchange agreed in principle, mapping understood
• Waiting for sample (meta)data set and agreement on exchange
mechanism
• AMDAR
• Mapping understood
 in-flight as gridded field of capabilities per fleet
 profiles (ascent/descent) as «virtual» fixed profilers of specific
fleet at airport
• (Meta)data sources not yet identified, no sample (meta)data
• WMO Radar DB
• Under investigation
• Regular integration planned

Representation of capabilities
• Capabilities stored as tuples of
•
•
•
•
•
•
•
Observed variable
{X, Y, Z}(t)
Observed from date
Observed until date
Uncertainty absolute
Observing cycle (including diurnal, seasonal availability)
Reporting latency
• Observation geometries such as profiles, lines or volumes
• need to be translated into such tuples
• specific method depends on available metadata, type of
observation (e.g., radio sonde, aircraft inflight, radar)

Expressing Capabilities of
remote-sensing instruments
Radar example
Station: point or collection of points in space (in blue for
radar) providing capabilities for a given variable.
Radar HR= f(x,y,z)
Radar VR= f(x,y,z)

(Gap) analysis (I)
• Scope
• Compare capabilities with requirements on global, regional, and
national scales
Variable
Vertical Layer
Horzontal coverage
Application area
• Purpose
• Know where gaps are
• Develop observing systems rationally and efficiently
• Discover capabilities that could serve a specific application

3. System selects observation

Shape files:

Example:

- Variable x
- Application area z
Results:
Capability from radar

4. System calculates observation capabilities for each grid cell or shape file:
HRi =(aij/n.of observations)1/2 or other statistic
VRi = vertical extent of layer/n. of observations
5. System compares for each grid cell or shape file capabilities with observational requirements
and displays results.
