From the solar radiation intensity measurements in LIVES range the erythemal Doses in the units of predefined Minimum Erythemal Doses per hour (MED/Hr) are derived and their characteristics are studied during this period. It is found that maximum MED values reached during the month of December 1998 with its magnitude 4.00MED/Hr at local noon of 1st December 1998. The solar radiation intensities in the VIS-NIR range are used to derive and study the aerosol optical depths over Antarctica. From these studies it is found that the representative optical depths at 368, 500, 675 and 778 nm wavelengths, the corresponding optical depths are 0.75, 0.25, 0.097 and 0.048 respectively, which shows that at Antarctica the optical depth increases with decreasing wavelength. The present human concern about the environment is inciting the scientific community to probe and characterise the different aspects of environment. The multifaceted involvement of the solar radiation in affecting the environment makes the solar radiation as an important environmental parameter. The solar radiation passes through the earths atmosphere before reaching the earth surface. Any observation of solar radiation at earth surface will be having the signatures of the processes involved between the solar radiation and earth atmosphere. The Ultra-Violet solar radiations, which are sensitive to their interactions with the ozone gas present in the stratosphere, carry to the ground the signatures of the variabilities in the concentrations of ozone gas in the stratosphere. After the discovery of the ozone hole over Antarctica, the study of these ultraviolet radiations over Antarctica was recommended very strongly.
