Atmospheric Trace Molecule Spectroscopy ATMOS

During the last 15 years Fourier transform spectrometers have been used successfully to sound the stratosphere and upper troposphere. One of the most important successes has been the Atmospheric Trace MOlecule Spectroscopy (ATMOS) project (e.g. Farmer et al., 1987 Gunson et al., 1996). The ATMOS instrument flew aboard Spacelab 3 and the Atmospheric Laboratory for Applications and Science (ATLAS) Space Shuttle missions (Table 1). ATMOS performed solar occultation measurements and a variety of trace gases in the upper troposphere and stratosphere have been retrieved. 

The limb-tangent solar absorption method has been used to obtain profiles of trace gases in the Earth s stratosphere. An example of an investigation using this approach is the Atmospheric Trace Molecule Spectroscopy (ATMOS) Michelson interferometer carried on the Shuttle-bome Spacelab 3 in 1985. A large number of atmospheric transmission spectra were acquired in the 600 to 4700 cm spectral region (Earmer Raper, 1986 Farmer Norton, 1989). Vertical profiles of various trace gases have been obtained from these data (Park et al., 1986).
