The latest state-of-art equipment called Brewer Ozone Spectrophotometer has been installed at Maitri, the permanent Indian Scientific Research Station, Antarctica in July 1999 to monitor total ozone, damaging part of ultra-violet radiation (D-UV), sulphur dioxide (SO2) and nitrogen dioxide (NO2). The depletion of ozone and its fluctuation were monitored day by day during Antarctic spring season (August-October). The data collected during the year 2000 are analysed in this paper. 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 the spring season. The measurements confirm the existence of 'Ozone Hole' over Antarctica 2000. The measurements of SO2 and NO2 at Maitri show very low values.
