Abstract :
The significant fluctuation of ozone content under altitude h>20 km above sea level has been connected with the atmosphere dynamics, and particularly with the stratospheric warmings and with internal gravitational waves. The galactic cosmic rays (GCR) are considered as the main reason of the ionization of atmospheric gas constituents. Among different methods of stratospheric ozone measurements, microwave radiometry observations make it possible to conduct long time middle atmosphere ozone monitoring under high time and space resolution. Besides, this method seems to be mostly effective in the studies of the link between solar activity and ozone variations at the earth stratosphere and lower mesophere. The following results have been observed at polar and moderate lattitude during 23rd solar cycle: there were, after proton events, a short time decrement of ozone content at certain elevation. The ozone variations are good correlated with the proton flux fluctuations just at the time of enhanced solar activity. However, the correlation coefficient between averaged values of O3density and mean proton fluxes is basically, statistically insignificant.
