Abstract :
The Helsinki University of Technology (HUT) ground-based 110 GHz radiometer has been operated since 1996 at the Sodankyla Observatory (latitude 67N in northern Finland) in collaboration between Laboratory of Space Technology and Finnish Meteorological Institute. Based on these data, short-term (diurnal) and long-term (seasonal and annual) variation of stratospheric ozone in northern Finland is discussed, especially for altitudes 35 to 70 km
