The Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment uses a
Fourier-transform spectrometer on board the Space Shuttle to record in
frared solar occultation spectra of the atmosphere at 0.01-cm(-1) reso
lution. The current version of the molecular spectroscopic database us
ed for the analysis of the data obtained during three Space Shuttle mi
ssions between 1992 and 1994 is described. It is an extension of the e
ffort first described by Brown et al. [Appl. Opt. 26, 5154 (1987)] to
maintain an up-to-date database for the ATMOS experiment. The three-pa
rt ATMOS compilation contains Line parameters of 49 molecular species
between 0 and 10000 cm(-1), The main list, with nearly 700,000 entries
, is an updated version of the HITRAN 1992 database. The second compil
ation contains supplemental line parameters, and the third set consist
s of absorption cross sections to represent the unresolvable features
of heavy molecules. The differences between the ATMOS database and oth
er public compilations are discussed.
