12. Conclusions & Outlook What? Where? How? Why? API
January 2, 2019
Conclusions & Outlook
What? Where? How? Why?
Integration of OSCAR components by 2018 T= 17 °C
T=17°C
T=17°C
API
Based on OGC/ISO O&M Ready for testing
Operational since 2 May 2016
WIGOS Metadata Standard
Enable adequate use of observations
Evolve observing systems rationally
… nationally, regionally, world-wide
Approved by Cg-17
Amendments by CBS-16
Expected in 2017
Start with a simple number: 17 … what is it?
Ah, it’s temperature … but in what unit?
Oh, there’s more temperature observations , all 17°C … need to know where, how, why!
WIGOS Metadata Standard specifies essential metadata elements that give necessary context to observations,
to make adequate use of observations,
to support gap analysis to evolve observing systems rationally
Four OSCAR components support the WIGOS RRR, a cycle of requirements specification, catalogueing capabilities, and gap analysis
OSCAR/Requirements
OSCAR/Space
OSCAR/Surface
OSCAR/Analysis (a future module)
OSCAR/Surface has been developed in a joint venture of WMO and MeteoSwiss, and has been operational since May 2016.
The web interface is a reference implementation of the WIGOS Metadata Standard and brings together information on observing systems on land, in the air and at sea. Humans can interact with the application and provide metadata manually.
Once the machine-to-machine interface to OSCAR/Surface is ready, it will be possible to document large observing systems comprehensively.
