Ozonesondes measure the amount of ozone in the atmosphere by leading the outside air through a pump to two electrochemical cells in an isolation box, in which a chemical reaction of the ozone molecules generates an elect…
ric current, which is a measure of the ozone concentration in the atmosphere. These ozonesondes are launched with meteorological weather balloons and the measured currents are transmitted via a numerical interface to a radiosonde (= a mini weather station), which in turn transmits these data to the
radiosounding receiving station at Uccle. Batteries ensure the alimentation of the ozonesonde's pump. The need for these measurements lies in one of the core tasks of the RMI, namely observing the vertical distribution of ozone concentratio
