Guidance on WIGOS station identifiers Draft available on web ( Identifiers) Identifiers Issuer of Identifier ISO 3 digit code for Member countries Listed in Table for (known) WMO and partner programmes Approaches to allocating station identifiers Issue number record re-use of existing identifiers sub-delegate to national organizations Representing in TDCF reports Not possible in TAC ICG-WIGOS-5: WIGOS station identifiers 7
Recommendation Background A station can have many WIGOS identifiers Recommend 1.Members do not issue new WIGOS identifiers for a station that already has one. 2.WIGOS provides a look up for equivalent station identifiers 3.For observation reports, use the WIGOS identifier associated with the Programme requiring the report ICG-WIGOS-5: WIGOS station identifiers 8

Exchanging WIGOS metadata WIGOS metadata records evolution of observing conditions over time Divided into groups where (most) metadata remains unchanged Split into sub-groups corresponding to different observation types Some components of metadata are the same across many metadata records For example the contact details for the manager of a group of observing sites Proposal – a standard set of identifiers to allow these to be referred to unambiguously ICG-WIGOS-5: WIGOS station identifiers 13

Request Document in Guide to WIGOS? Manual on Codes? Is the approach right? The identifiers look like URLs but do not have to “work” May need to use something other than ICG-WIGOS-5: WIGOS station identifiers 15
