【摘要】The ultraviolet (UV) region of electromagnetic radiation from sun occupies a section of wavelengths ranging from 400 to 10 nm. It is highly ionizing and activates many chemical processes on different types of materials and living beings. As a function of its effects on the biosphere; the UV radiation regions are arbitrarily called UV-A; UV-B and UV-C. A global scale called Solar Ultra Violet Index (UVI) is used to describe the level of UV radiation on the biosphere. The amount of UV radiation at different places on the earth depends on the position of the sun during the day and the season of the year. A decline in the amount of total ozone content (TOC) at a particular time also leads to an increase in UV radiation at that time. The present study has analyzed the variation of TOC and UVI over different Indian region using total ozone data from OMI and erythemal UV irradiance (converted to UV index) from TEMIS for the 2006-2010 period.
