50 years of ozonesonde measurements at Uccle
On 19 September 2019, the RMI hosted a scientific symposium celebrating the 50 years of ozonesonde measurements at Uccle.
After some years of testing - the earliest ozonesonde measurements at Uccle in the WOUDC database date back to 1965, 1966 and 1967 - the operational ozonesonde programme at the Royal Meteorological Institute (RMI) of Belgium in Uccle started in January 1969, with a launch frequency of three times a week, year around. In 2019, after more than 6800 launches covering 50 years of measurements, we wanted to highlight the value of this tremendous effort, of this long-term dataset, for the past, present and future.
Therefore, a celebration event was organized at the Uccle launch site on Thursday, 19 September 2019. Since ozone is a trace gas that has different impacts on life on Earth, depending on its location in the atmosphere (UV blocker, greenhouse gas, air quality), the event was open to a wide range of interested people, from data users, policy makers, environmental agencies and the media, to of course scientists with interests in ozone research. A total of 95 participants attended the meeting, about two third from Belgium, but also from neighbouring countries (Netherlands, France, Germany), other European countries (Spain, Poland, Czech Republic, Switzerland, Italy), and even from Canada and the United States.
