Topics
- Mars TES Spectra More information in the readme file.
- FTIR Tropical Pacific downwelling IR spectra. Not used in the text or problems currently, but very interesting. Information in the readme file.
- HITRAN spectral data. This is used in the summary of spectral absorption characteristics of selected gases. This is also the database that is read by the ChapterScript Pytran.py, and is used for preparing exponential sum tables. The key spectral line data, arranged by molecules, is in the directory ByMolecule. Information on which molecule is in each file is given here, and papers describing the database are here and here. The general contents of the full database are summarized here. Note that this is a subset of the full database, and is not the most up-to-date version. If you are doing research using spectroscopic data, once you have learned the basics by working with this version, you should go get the most current version. To get the most current version of the spectral data, consult the HITRAN web site. The newest version of the database also includes collisional continuum data (except, regrettably, for water vapor)
- Exoponential sum tables. These are read by the homebrew radiation code, and used as the basis of the real-gas infrared radiative transfer calculations. Ordinarily, you can just use these tables for doing calculations in the problems, but you can also generate new tables of this type from the HITRAN spectral database using Pytran.py.
- Miscellaneous infrared absorption data. The Crisp/Kasting CO2 continum absorption is here. The set of Courtin gaseous collisional continuum data (mostly directed at Titan applications) is here (information in the readme file). Water ice absorption is here and liquid water absorption is here.
