Brief Description (Abstract):
The ozone depletion in general and ozone hole phenomenon over Antarctica during spring in particular has generated a surge of interest in the measurement of ozone using various techniques. A High-Tech Laser Heterodyne System using a 1 GHz Acousto-optic spectrometer as back end has been designed and developed at National Physical Laboratory, New Delhi to monitor ozone and other trace species in the atmosphere. The Laser Heterodyne System has been successfully operated at Maitri Lo obtain ozone line spectra at 1043.1775 cm with an ultra high spectral resolution. The line spectra thus obtained with high spectral resolution in trun has been used to get vertical profiles of ozone in the atmosphere using inversion technique developed at NPL for Antarctic conditions. A liquid nitrogen plant was also installed at Maitri. In the present communication the salient feature of the Laser Heterodyne System, Acousto-optic spectrometer, liquid nitrogen plant and results obtained are discussed in detail
Status: Completed
Purpose: To study of minor constituents in the atmosphere is of vital interest to understand the structure of troposhere and stratosphere.
