Change duplicate notations in tables 1-01-* and 5-02-*

[amilan17]

Initial request

OSCAR/Surface parser currently only looks at the last element of a URL and expects a notation that is unique across the entire “namespace” of the element. Thus, the artificial separation of ObservedVariable* and ObservingMethod* into several code tables is essentially ignored by OSCAR/surface.

Amendment details

updated 15 Aug 2023

supersede with new notations to avoid duplicates across similar tables

table	notation	name
5-02-01	344 417	GC-CVAFS
5-02-01	345 418	GC-TCD
5-02-05	346 419	Frequency domain reflectometry
5-02-05	347 420	Gamma-ray attenuation
5-02-05	348 421	Non-recording gauge
5-02-05	349 422	Staff gauge

table	notation	name
1-01-01	12245 12320	C3H2F6 (1,1,1,3,3,3-hexafluoropropane, HFC-236fa)
1-01-01	12246 12321	Tellurium [Te-131]
1-01-03	12244 12319	N2, Ar
1-01-05	12247 12322	Stream velocity
1-01-05	12248 12323	Stream mean velocity
1-01-05	12249 12324	Stream surface velocity
1-01-05	12251 12325	Water surface slope

Comments

It might be useful to develop some best practices on how to assign numerical notations in such a way that will ensure no duplication, rather than querying all tables to find out what number is the highest.

I accept some of the (shared) responsibility for not having scrutinized these tables sufficiently before the previous amendments went to FT. These duplicate notations - even though in different name spaces - create difficulties for OSCAR/Surface, but they may also lead to risk of confusion and errors of the users. We should keep the notations unique acroos these sub-tables. The odds are that the effect will be minimal if quickly reacted to, which means I would favor a correction of the codes registry using the 'experimental' flag, in combination with an announcement in the operational WMO letter, and followed of course with a regular CR as part of FT-2023-2.

• (Joerg) would like to make these changes NOW in the codes registry with 'experimental' status and then introduce it to FT for formal approval;
• Team approves of this approach.

Branch is updated but I think this needs to go through the official fast-track procedure because the codes with the old notations will be superseded by the codes with the new notations. I can't simply change the notation in the registry and change the status to 'experimental'. I can only add new notations with the status of 'experimental' and change the status of the superseded codes to 'superseded'.

The only value that I think I can fix now, is fog collection, because it used to be polarized lidar (same notation, same table).

+1 on going through the FT ... but, technically, you can make the changes already know, and tag them with experimental. Am I missing something?

Anna talk with Mark to see if we can have a new status code called 'experimentally-deprecated' or something like that.

@amilan17 to update branch

[amilan17]

@jbianchi81 -- I need to change the notations for some of the hydro methods that were recently added. They are not implemented in OSCAR/Surface yet and I'm hoping that the hydro community is not using them yet either. Can you confirm?

Yes, you may proceed

[amilan17]

@jbianchi81 Thank you for your quick response. I have the same question for observed variables...

Discovered more dupe notations in 1-01-01 and 1-01-05 (introduced in FT2023-1). I will update the FT2023-1 release BEFORE I update the codes registry!
