Abstract :
[en] The german HGF virtual institute PEP (Pole-Equator-Pole) has been established in 2004 in order to investigate the variability of atmospheric trace constituents along a north-south transection. Within PEP the HGF centres AWI and FZK as well as the german Universities of Bremen, Karlsruhe and Potsdam combine their knowledge and capabilities in ground-based measurements and global and regional modelling of atmospheric trace constituents and aerosols. Here we present results of long-term measurements of the stratospheric column of HCl, ClONO2, HF, and O3 obtained at the different PEP stations in the northern hemisphere and in addtion at Jungfraujoch. All stations are affiliated to the NDACC (Network for the Detection of Atmospheric Composition Change). The measured time series are compared with long-term model calculations performed with a state of the art 2-D model of the University of Bremen and the 3-D CTM KASIMA. Please note, that the lowest altitude for the determination of the total columns is about 7 km leading to a slight underestimation w.r.t. the measurements.
