Brief Description (Abstract):

The measurements of ultra-high resolution absorption line spectra of ozone at V3 band near 9.5(µm) has been obtained by laser heterodyne spectrometer using carbon dioxide laser as a local oscillator in Maitri (70? 46' S, 11?45' E) Antarctica. The observations were made from 15 Jan. to 20 Feb. 95 on clear available sunny days. The vertical concentration profile of ozone has been retrieved through inversion of the measured absorption line profile. In the present communication results obtained are discussed.

Status: Completed

Purpose: In the recent years the global ozone depletion and ozone hole phenomenon over Antarctica has intensified ozone research around the world. Ozone, a minor constituents of the atmosphere is important because it protects life on the earth from harmful part of solar ultra-violet radiation and also significant for controlling stratospheric temperature. Total ozone in the atmosphere has been measured globally with the help of Dobson- spectrometers by monitoring the absorption of solar ultra-violet radiation at selected wavelengths in 280-340 nm wavelength range. Ozone measurements has also been carried out by ozonesonds placed on rockets and balloons. On global basis ozone has been monitored by satellite using total ozone mapping spectrometers (TOMS) also.
