The purpose of this project is to develop and enhance the HITRAN molecular spectroscopic database and associated software to support the observational programs of EOS. In particular, the focus is on the EOS projects: the Atmospheric Infrared Sounder (AIRS), the HIgh-Resolution Dynamics Limb Sounder (HIRDLS), Measurements of POllution in the Troposphere (MOPITT), the Tropospheric Emission Spectrometer (TES), and the Stratospheric Aerosol and Gas Experiment (SAGE III). The date requirements of these programs in terms of spectroscopy are varied, but usually call for additional spectral parameters or improvements to existing molecular bands. In addition, cross-section data for heavier molecular species must be expanded and made amenable to modeling in remote sensing. Other issues that must be addressed for the EOS projects, coming withing the scope of the HITRAN compilation, are aerosol indicies of refraction, continuum modeling, line-mixing and similar line-shape problems, collision-induced absorption parameters, and high-temperature parameters. The effort in the proposed project also includes developing software and distribution to make access, manipulation, and use of HITRAN functional to the EOS program.
