Transition to Automatic Stations in the OSCAR System

Transition to Automatic Stations in the OSCAR System

Dear Colleagues 

In Armenia, we have installed automatic weather stations parallel to our existing manual meteorological stations, which will gradually replace them. During the period of parallel operation, we have verified the accuracy of the data received, and since it meets the required standards, we plan to close some of the manual stations in two months, keeping only the automatic ones. Among these stations, there are some that participate in global/regional exchanges.

I would appreciate your guidance on the next steps. Specifically, can we close the existing stations in the OSCAR system, register the automatic stations, and assign them the same indexes as they currently have, given that they are located at the same coordinates?

Additionally, how should we manage the parallel stations during this transition period?

How to deal with transitioning to AWS from manual is a tricky process to make sure that the metadata is retained.
This is one suggestion that we have used in Australia.
If the existing manual station is still in the 20000 series, e.g. 0-200000-X-12345
You can then enter a new station in Oscar/Surface 0-ABC-X-12345, where ABC is the country identifier, which you do not tick "Intended for international exchange"
Once you have confirmed that the new station (AWS) is accurate, you then tick the box "Intended for international exchange".
For the original manual station, you untick the box "Intended for international exchange".
This way the data in the TAC code still gets reported against the same 12345 number, but it is linked to the new WSI which point to an AWS in OSCAR/Surface.

Dear Karl,

Thank you for your explanation and for sharing your experience.

Best regards,

Dear Karl, but is the transition on OSCAR from the old 20000 series code, e.g. 0-200000-X-12345 to the new Oscar/Surface 0-ABC-X-12345 mandatory for all stations, both the manual ones and the new AWS that replace them? Is there a regulation regarding this?

Dear Mario,

There is no requirement to change stations in OSCAR/Surface from the 20000 series into something else.

The approach described for Australia could be followed when having two stations (two observing equipment) installed side-by-side, registered in OSCAR/Surface. What Karl mentioned is an example of two stations running simultaneously at the same site, when one is under testing before replacing the other one that has been operational - @Karl, please correct me if I'm wrong.

Another, different approach, could be to register the two stations while declaring the new station as "Planned", or as "Pre-operational" or as "Stand-by", and declaring the other station as "Operational"; Please check all the possible entries of "Station/Platform operating status" code list here:  https://codes.wmo.int/wmdr/_ReportingStatus.

Thank you, kind regards,

Luis

Ok dear Luis, so there is no regulation regarding this?
