Ozone measurements began in 1982 at the Georg von Neumayer Station on the Ekstrom Ice Shelf in Antarctica and continued until 1996. The station was about 15 km from the ice edge. In the first year, a so-called trace substance observatory was set up 1.5 km south of the station by the University of Heidelberg (Weller et al. 2007) in order to be able to take a wide variety of air-chemical samples. Some experience had to be gained under the extreme conditions. For some devices, frost settled in the air intake shaft. The ozone machine had its own Teflon suction line, which worked without any problems. The bubbler, on the other hand, was sensitive to direct sunlight, causing the display to change erratically. This was successfully prevented by a cardboard sunshade. An aerosol filter was installed at the outlet of the device in order to separate the solution droplets formed in the aerator so that aerosol measuring devices and in particular a particle counter was not disturbed. The ozone device also survived an ...
