Paper Abstract

Heterodyne detection of ozone in the stratosphere has been demonstrated using a tunable single sideband CO2 laser as the local oscillator and solar radiation acquired at ground level. Two unblended strong O3 vibrational- rotational transitions at 1047.209 and 1047.225 cm-1 which were offset at 10.66 and 11.12 GHz away from the CO2 carrier 9P20 were observed. High resolution measurements at 5 MHz (0.00017 cm-1) with a signal to noise ratio of 100:1 were obtained. The measured FWHM linewidths for these lines are about approximately equals 65 MHz. Retrieved data indicated magnitude of absorption is consistent with the anticipated integrated O3 column density from the stratospheric region.
