The meteorological observatory Neumayer typically launches one radiosonde per day around 12UTC. At least weekly the sonde has an ozone sensor attached. Sondes are released from the roof of the station building. The measurement interval of the raw data is typically 1s. Data is quality controlled: Erroneous data is removed (technical issues). Partial pressure ozone is manually validated for plausibility.

Station altitude is 43 m, the launch site is located 25 m higher at 68 m above sea level. The first row of each sounding holds surface data for TTT, RH, ff and dd, which is not acquired by the radiosonde. The measuring height of TTT and RH is 2m, and 10m for dd and ff. The raw data of the sounding on 2019-05-22T12:00 lacks data in the table "SynchronisedSoundingData" for Altitude up to 1150m. This sounding was complemented with data from the data tables "RawPtu", "GpsResults", "WindResults". The estimated uncertainties up to Altitude 1150m are: Altitude +-7m, h geom derived from GPS receiver mounted on radiosonde derived from GPS receiver mounted on radiosonde with respect to WGS84 reference ellipsoid +-16m, PPPP +3hPa, TTT +-0.7°C, RH +-6%, dd +-3°, ff 1.5m/s.
