| Abstract |
Stratospheric ozone shields the surface of the Earth from
the ultraviolet radiation of the Sun and thus permits
biological life in its present form. Satellite and
ground-based observations show ozone amounts to decrease.
The main objective of this project is to perform field
measurements at high latitudes yielding data which help
to understand how polar stratospheric clouds and aerosols
affect the nitrogen partitioning and generate active
chlorine, which enters in the chemistry of the
stratospheric ozone loss.
