At present, the research group consists of 11 employees. The ozone research is based on observations, data on stratospheric dynamics and models of stratospheric chemistry and dynamics.
Special emphasis is put on Arctic and Antarctic latitudes.
At Antarctica, Finnish-Argentine ozone sounding and total ozone observations have been performed since 1988. The research group has been responsible for establishing UV monitoring network in Finland. In this work, special attention has been paid on the calibration and maintenance of the instruments. The UV research is based on measurements of UV radiation, radiative transfer models and several ancillary measurements of importance for radiative transfer.
