GLORIA-B launched on stratospheric balloon in Canada

This flight extends the time series of KIT measurements with specially developed IR remote sensing spectrometers on stratospheric balloons. Since 1989, 26 large balloon launches were carried out to investigate the chemical composition of the atmosphere (up to ~40 km) under changing conditions by climate change.

Diurnal variations of BrONO2 observed by MIPAS-B at midlatitudes and in the Arctic

The main goal of these observations was to check the current understanding of stratospheric bromine chemistry and to estimate the amount of lower-stratospheric inorganic bromine, which has been assessed to be about 21–25 pptv.
