| Abstract | The solar activity effects on Earths atmosphere and the modulation of the solar cycle signal on the UV-B levels play an import role on life systems; this is because this radiation range acts directly on organic molecules as DNA causing normally irreversible damages. It has a strong spectral dependency, with variations of about 15% at the spectral range 175-205 nm, 4-7% at 205-250 nm and 0.5% at 250-400 nm, while total solar irradiance has a variation about 0.1 % with the 11-years Solar Cycle. Furthermore, the Solar Cycle variations of UV radiation demonstrate latitude and seasonal dependencies. Correlations between measures of the solar radio flux per unit frequency at a wavelength of 10.7cm and UV-B levels from Brewer spectrophotometers at the INPEs Southern Space Observatory (29°S, 53°W), South of Brazil, from 1996 to 2007, were performed. UV-B radiation at this site presents typical season profile with lower values in Junes (6.8-0.5)-10³ mW/m2 and highest in Januaries (34.7+/-7.9)+/-10³ mW/m2. The amplitude of UV-B variation with the solar cycle has been estimated using wavelets as mathematical toll. The differences in UV-B radiation between maximum and minimum solar cycles were estimated, using yearly averages of UV-B radiation. The results with the pertinent mathematical calculations and interpretation are reported. |
