1995 Atmospheric Trace Molecule Spectroscopy (ATMOS) linelist

Area of Science:

• Atmospheric science
• Spectroscopy
• Planetary science

Background:

• The Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment utilizes infrared solar occultation spectroscopy.
• Accurate molecular spectroscopic data is crucial for analyzing atmospheric composition from space-based measurements.
• Previous versions of the ATMOS database have been instrumental in atmospheric research.

Purpose of the Study:

• To describe the current molecular spectroscopic database used for analyzing ATMOS data.
• To provide an updated compilation of line parameters for 49 molecular species.
• To detail the structure and content of the ATMOS database, including differences from other compilations.

Main Methods:

• Utilizing a Fourier-transform spectrometer on the Space Shuttle to record atmospheric spectra.
• Developing and maintaining an extended molecular spectroscopic database.
• Compiling line parameters for 49 molecular species across a wide spectral range (0-10000 cm(-1)).

Main Results:

• The ATMOS database is a three-part compilation including a main list of nearly 700,000 entries, updated from HITRAN 1992.
• Supplemental line parameters and absorption cross-sections for heavy molecules are included.
• The database covers spectral information for 49 molecular species relevant to atmospheric studies.

Conclusions:

• The described ATMOS database provides a comprehensive resource for the analysis of infrared solar occultation spectra.
• This updated database enhances the accuracy of atmospheric trace molecule identification and quantification.
• The work facilitates further research in atmospheric science and remote sensing.
