Paper Abstract

The objective of the ATMOS experiment is to measure the concentrations and distributions of gases in the middle and upper atmosphere (10 km to 120 km) by infrared absorption spectroscopy. In 1985, during NASA's Spacelab 3 mission, high resolution (0.01 cm-1) infrared occultation spectra of the atmosphere were recorded using a modified Michelson interferometer orbiting on board the space shuttle. With the sun as the radiation source, a single spectrum was obtained every 2.2 seconds with signal to noise ratios of 100:1 or better. Many disciplines and technologies were combined to produce this state-of-the-art NASA experiment. An overview of the data analysis techniques, implications for molecular spectroscopy and results obtained from the SL3 mission is presented.
