The meteorological sounding record of 1965–92 and the ozone sounding record of 1988–92 at Sodankylä have been studied. In early 1992 the stratospheric temperatures and geopotential heights were lower than the 1965‐92 mean, especially in January. The occurrence of 50 hPa level temperatures below 195 K in January has increased considerably starting from the early 1980's up to a maximum in 1992. The partial pressures of stratospheric ozone in January–March 1992 were 17% lower than the 1988–91 averages with the largest relative monthly mean deviations up to −33% between the 13–17 km levels.
