Dear Kemal,
We are working with Meteoswiss to collect detailed information about the metadata records of the stations you mention.
We can discuss them together once we have those details available.
Kindly note that most of the 14 stations are declared for international exchange in OSCAR/Surface and some of them seem to be actually reporting data, according to the WDQMS webtool (https://wdqms.wmo.int/).Regarding your last question, please allow me to remind that WMO Members are responsible to verify and correct/update, via their National Focal Points on OSCAR/Surface (or through their delegated contacts, e.g. metadata editors), the WIGOS metadata from all stations in their countries/territories.
Best regards,
Luis
