Daily total ozone measurements are carried out in Tomsk, Central Siberia using Brewer Mark-IV spectrophotometer 049 since 2003. This instrument was used at Heiss Island, Franz Josef Land, Russia in 1988-1994. The accuracy of routine total ozone observations at direct sun measurements is 2-3%. Under cloudless conditions at air mass factor less than 4, the accuracy of total ozone direct sun measurements approaches 1%, while the accuracy of direct moon observations is 2-3%. SAOZ (Systeme d'Analyse par Observation Zenitale) is UV-visible (300-650 nm) diode array spectrometer developed at the Service d'Aeronomie, CNRS, France for monitoring stratospheric ozone and NO2. Zenith sky measurements of atmospheric gases at twilight (86°< solar zenith angle < 91°) are used. There are 17 SAOZ instruments in SAOZ network around the world. Ttree instruments are located at the Arctic Circle in Russia at Zhigansk since 1992, Salekhard since 1998 and Anadyr station in Far East, Russia since January 2011. Accuracy of total ozone measurements is 6% and 10% for nitrogen dioxide observations. The results of ozone monitoring are compared with data of ozone measurements in polar vortex conditions at these stations are in SAOZ database. Currently, we use 2Z-ECC ozonesondes for ozone profile observations in winter/spring periods at Salekhard aerological station. The results of ozonesounding at Salekhard station are in NDACC database. The recent results of Brewer, SAOZ total ozone observations in Siberia and Far East, Russia, data of ozone profile observations in western Siberia at Salekhard aerological station in winter/spring sesons of 2011 and 2012 will be presented and discussed.
