Sondes are released from the roof of the station building. The measurement interval of the raw data is typically 1s. All data published here is left as recorded, no quality control was applied.

Data files were produced by a proprietary radiosounding system from Vaisala. The format is referred to as "mwx". Technically, the files are zip files comprising several xml-documents.
