The use of visible spectroscopy makes it possible to measure stratospheric constituents when Solar Zenith Angle (SZA) is as large as 93[degree]. This fact allows the daily measurements of ozone and other species throughout the year at and beyond the latitudes of the polar circle. Because the visible spectroscopy is a new technique in ozone monitoring, it is useful to compare it with the classical uv spectroscopy. At Sodankylae the widely-used SAOZ uv/visible spectrophotometer (Systeme d'Analyse et d'Observations Zenithales) and the modern uv spectrophotometer Brewer have been measuring side by side since early 1990. This paper reports the first long-term intercomparison between the daily total ozone values measured by the SAOZ and the Brewer covering the period from February 1990 to June 1991. As a reference the intercomparison between the Brewer and TOMS (Total Ozone Mapping Spectrometer) instruments from May 1988 to December 1991 is also reported. 13 refs., 4 figs., 2 tabs.
