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. Temperature sensor during sounding on 2020-09-19T12:00 is suspected to have failed between 16268m and approximately 18150m Altitude.
