| Summary: | The study of various minor constituents in the atmosphere plays an important role in the understanding of physics, chemistry, dynamics and radiation budget of the atmosphere. These trace species have temporal as well as spatial variation and therefore the knowledge of latitudinal distribution of these species is of great significance. Keeping this in view a highly sophisticated and microprocessor based compact sun photometer consisting of five filter channels at 300, 305, 312, 940 and 1020 nm was used to measure column ozone, water vapour in addition to various other parameters such as UV-B radiation, near IR radiation, aerosol optical depth etc. The measurements were made from Goa, India (15° 24´ N, 73° 42´ E) to Maitri, Antarctica ( 70° 46´ S, 11° 45´ E) over Indian Ocean during 16th Indian Scientific Expedition to Antarctica (December 1996-March 1997). It was found that water vapour decreased while total ozone increased as the ship moved towards the coldest, the windiest and the largest icy continent i.e. Antarctica. |
