The Solar Cycle and Cosmic Ray Particles Have Direct Influence on Stratospheric Ozone Variation?

We analyze in this work three available sets of stratospheric ozone measurements obtained by ground UV sun spectrophotometer type Dobson and low energy stratospheric cosmic rays in the period from 1957 until 1995. By the analysis of these sets of ozone data, we can see a decreasing intensity at all these latitudes (Belsk, Tbilisi and C. Paulista), given a global mean rate - 10 % during the last three solar cycles. We saw also correlations with cosmic rays measurements in the stratosphere, ozone variations and sunspot number.
