AEDC Calculated Spectra

Transmission spectra were calculated using the HITRAN96 spectral database and a modified version of the Fast Atmospheric Spectral Code (FASCODE). These trasmission spectra were degraded using triangle apodization and converted to absorbance (base 10). Pressure was set to 760 mm Hg (1 Atmosphere). It should be noted that these results are calculated spectra based on fundamental molecular parameters typically measured by high resolution spectroscopic techniques. The HITRAN96 data base is primarily used for atmospheric absorption calculations and was not initially intended for elevated temperature calculations. However, these spectra should represent to a high degree of accuracy the spectra anticipated up to 500K. Any error between the calculated spectrum and the true spectrum will normally increase with increasing temperature.

Spectra at other resolutions and/or apodizations can be obtained by downloading the .125cm-1 resolution boxcar apodization spectrum and using the DERESOLVE program.
