Brief Description (Abstract):

Total column ozone has been measured using Microtop Sunphotometer at Maitri, Antarctica, during 21st Indian Antarctic Scientific Expedition (2002 ? 2003). The Maitri observations were also compared with TOMs data as well as nearby Russian station data and were found to be in good agreement. The water vapour has also been measured on the way from Goa, India to Maitri, Antarctica on the ship Magdalena Oldendroff. The ozone hole during spring of 2002 over Maitri did something unusual reflecting the unusual behaviour of the planetary waves in the Southern Hemisphere, which confirmed the roll of capricious weather in the opining and closing of ozone hole. The observation shows that the ozone hole in the year 2002 was not as deep as that of the previous years. The minimum value of total ozone of about 185 DU was observed in the last week of September during 2002 and exceptionally high values of about 420 DU were observed during the ozone hole period.

Status: Completed

Purpose: Ozone is one of the most important constituents in the atmosphere and in spite of its low concentration, a few ppmv, it plays an important role not only in the chemistry of this region but also it affects dynamics and biological activity near the surface. The amount of ozone over any particular place depends not only on photochemical balance, but also on the stratospheric climate, the winds that transport the ozone. The stratosphere itself is dependent on ozone for its existence. The energy absorbed by ozone in the course of creation and destruction of its layer warms the surrounding atmosphere creating temperature inversion.
