Abstract
We conducted an earth-satellite laser long-path absorption experiment using the Retroreflector in Space on the advanced earth observing satellite, which was launched on August 17, 1996 by the National Space Development Agency of Japan. Two single-longitudinal-mode transverse, electric, atmospheric (TEA) CO2 lasers were used in the spectroscopic measurement of atmospheric trace species. One TEA laser was used to measure the absorption of the ozone, and the other to record a reference signal. We measured the absorption spectrum of the atmosphere using the Doppler shift of reflected beam caused by the satellite's movement. The ozone spectrum was successfully measured using the 10R(24) line of 13CO2 and the 9P(24) line of 12CO2. We studied the measurement error and reduced it by adding a spatial filter to the transmitter optics.
