RMi Seminar: Total Ozone, UV and radiosonde measurements at Princess Elisabeth Station, Antarctica

Seminar by Dr. Alexander MANGOLD

Title: Total Ozone, UV and radiosonde measurements at Princess Elisabeth Station, Antarctica


This presentation gives the opportunity to present some results of RMI’s scientific activities at the Belgian Antarctic research station Princess Elisabeth (PEA) in East Antarctica.
Since January 2011 RMI has been operated a Brewer ozone spectrophotometer for measuring the total ozone column and UV spectra (283 to 363 nm) during austral summers at the Belgian research station. We will present an overview of the measurement results up to austral season 2021/22. UVI values, in particular in November and December, are strongly influenced by the variation of the total ozone column amount due to the yearly evolution of the Antarctic ozone hole. For example, in December 2020, with a long-lasting and deep Antarctic ozone, maximum UVI values between 13 and 14 and record low total ozone of below 150 Dobson Units were measured. We will also briefly compare the Brewer measurements with results of the MAXDOAS instrument installed at the station by IASB-BIRA.
Further, radio soundings by weather balloons (vertical profile of temperature, relative humidity, pressure, wind speed and direction up to around 25-30 km) have been launched during austral summers since season 2014/15 up to season 2021/22. The presentation will give an overview of the analyses on tropopause heights, inversion layers, wind conditions and tropospheric humidity. In addition, we will show results for integrated water vapour, derived from the radio soundings and from the collocated Cimel sunphotometer of IASB-BIRA.
