|Abstract:||The paper presents the effect of O3 depletion on night airglow emission of Li 6708 Å line at Dumdum (22.5°N, 88.5°E), India and Halley Bay (76°S, 27°W), a British Antarctic Service Station. Calculations based on chemical kinetics show that the airglow intensity of Li 6708 Å line will also be affected due to the depletion of O3 concentration. The nature of yearly variation and seasonal variation of intensity of Li 6708 Å line for the above two stations are shown and compared. It is shown that the rate of decrease of intensity of Li 6708 Å line is comparatively more at Halley Bay due to dramatic decrease of Antarctic O3 concentration.|
