Brief Description (Abstract):

Brewer Spectrophotometer has been installed at Maitri, the permanent Indian Scientific Research Station, Antarctica in July 1999 to measure total ozone, damaging ultra-violet radiation (D-UV), Sulphur dioxide (S02) and nitrogen dioxide (N02). The depletion of ozone and its fluctuation could be monitored day to day during Antarctic spring season (August-October). The data collected during the year 2000 are analyzed in this paper. The instrument Brewer spectrophotometer, (here after called Brewer) and its functions are described briefly. The values of total ozone and D-UV are compared in each month. The sudden increase or decrease of D-UV confirms further depletion or recovery of ozone in the successive days during spring. The measurements confirm the existence of 'Ozone Hole' over Antarctica during 2000. The measurements of S02 and N02 at Maitri show very low values.

Status: Completed

Purpose: It is now recognized that the significant fluctuations in atmospheric ozone and sulphur-dioxide concentrations are related to a variety of adverse environmental conditions. The ozone layer, which shields the earth from the harmful effects of solar ultra-violet (UV) radiation, is believed to be vulnerable to attack by chlorofluorocarbons (CFC) and other effluents. There is a general fear that the depletion of ozone concentration may alter the climatic pattern of the earth. Atmospheric sulphur dioxide is closely associated with acid rain phenomenon, which like ozone depletion has implications for the global environment.
