A. M. Zvyagintsev, N. S. Ivanova, G. M. Kruchenitskii, and I. N. Kuznetsova

The review is compiled based on the results of the operation of the system of monitoring total ozone over 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 methodological control of the Main Geophysical Observatory. The quality control of the entire system is performed based on observations from TOMS/EP satellite instruments. The basic observational TO data for each month of the second quarter of 2003 and for the quarter as a whole are summarized. Also are considered the results of regular observations of surface ozone, which have been carried out by the CAO in the forest zone of Moscow since 1991 and characterize the surface ozone concentration in central Russia.
