The review is based on the results of the operation of the Total Ozone (TO) Monitoring System in the CIS and Baltic countries functioning at the Central Aerological Observatory (CAO) in the operational regime. The Monitoring System uses data from the national network of M-124 filter ozonometers operating under the control of the Central Aerological Observatory. The quality control of the entire system is performed based on the TOMS/EP observations. The basic results of observations of total ozone for each month of the fourth quarter of 2003 and for the year as a whole are summarized. Furthermore, the features of the Antarctic spring ozone anomaly of 2003 are described. The recent results of regular observations of surface ozone concentration carried out by the CAO in the forest zone of Moscow and by the Upper-Volga Hydrometeorological Service in Niznii Novgorod are presented. These data characterize the state of the surface ozone layer in central regions of Russia.
