Brief Description (Abstract):

Total column ozone has been measured using Micro top Sun photometer at Maitri, Antarctica, during 21s 'and 22nd Indian Scientific Expedition to Antarctica. A comparison of TOC at Maitri over Schirmacher region of east Antarctica has been made to understand the behaviour of ozone hole in relation with stratospheric temperature. The observation showed relationship between the stratospheric temperature and TOC. The minimum values of TOC of about 185 DU and 126 DU were observed in the year 2002 and 2003 respectively during ozone hole period. The ozone hole values (less than 220 DU) during ozone hole period at Maitri was found out to be 20.7 % and 62.7 % in the year 2002 and 2003 respectively. Temporary sudden rise in TOC before the recovery period were also observed in both the years. In present communication the results obtained are discussed in detail.

Status: Completed

Purpose: Ozone is one of the most important greenhouse gas in the atmosphere and in spite of its low concentration, a few ppmv in mixing ratio, it plays an important role not only in the chemistry of this region but also it affects dynamics and biological activity near the surface.
