Key issues adressed by POLSTRACC are:
- Improving the understanding of chemical and physical processes involved in polar ozone loss
- Detailed investigation of structure and composition of the climate-sensitive UTLS region at high latitudes with focus on LMS region, the direct interface between stratosphere and tropopause
- Investigation of the outflow of the Arctic polar vortex into the LMS region, subsequent transport to lower latitudes and mixing with extra-vortex air
- Improving the knowledge on the properties of polar stratospheric clouds (PSCs) and vertical redistribution of nitrogen-containing compounds by PSC particles into the lower stratosphere
- Investigation of the role of Arctic cirrus clouds affecting the chemical composition and radiative budget of the Arctic UTLS
- Monitoring of the spatial and temporal variability of trace constituents and aerosols in the Arctic UTLS region during different phases of the polar winter
- Improving model simulations for evolution of the ozone layer and the knowledge on the role of the ULTS region in the climate system
