  1. Station Identifiers WMO; OBS

  2. WIGOS station identifiers WHY do we need station identifiers? WHAT is proposed? WHO is involved?

  3. Why do we need station identifiers? • To link observations and their metadata • Time series • Systematic errors • Avoid transmission of unchanging information • World Weather Watch • IIiii – have run out • Non-WWW • How refer to “partner” systems? IIiii D......D**** A1bwnbnbnb** IA...IA CCCC I6I6I6

  4. Principles No implicit meaning in station identifiers All contributing observations must have station identifier Unique – no station identifier refers to more than one station/platform Applicable to all observing systems operated by anyone Extensible – so do not need to issue new identifiers if system needs to be expanded Absorb existing systems for identifiers What is proposed?

  5. Proposed structure – WIGOS Station Identifier

  6. Examples – “import” WWW identifiers

  7. Examples – new identifiers

  8. Who is involved? • Secretariat – transfer WWW into system • Operators – provide WIGOS observation metadata for each registered station • Permanent Representatives – issue (and record in WIGOS metadata “index”) • Perhaps (for discussion by ICG-WIGOS) • Approved international operators (eg CTBTO) • Self-registration of amateurs (eg Met Office WoW) • Self-registration of other operators

  9. Summary • Single system of station identifiers • Unique • Can absorb existing systems • “meaningless” • Extensible • Can • Delegate issuing numbers • Who can issue numbers?
