Ozone content over the Russian Federation in the third quarter of 2011

The review is compiled on the basis of the results of the operation of the total ozone (TO) monitoring in the CIS and Baltic countries functioning in the operational regime at the Central Aerological Observatory (CAO). The monitoring system uses the data from the national network with M-124 filter ozonometers under methodological supervision of the Main Geophysical Observatory. The quality of the functioning of the entire system is under operational control based on the observations obtained from the OMI satellite equipment (NASA, the United States). The basic TO observation data are generalized for each month of the third quarter of 2011 and for the quarter as a whole. Presented are also the results of regular observations of surface ozone content carried out at CAO in the woodland-park zone of Moscow since 1991 and characterizing the ozone state in the surface layer in Central Russian region.
