Update for HITRAN References

The sources for the 6 major parameters in the HITRAN database, as well as for the cross-sections data, are contained in a pdf file. This file is updated each time new or modified data are added to the compilation. The reference document can be downloaded here ( HITRAN References ) or in the HITRAN ftp site.

Update for C2H6 (Ethane)

The symmetry labeling of some of the ethane lines in the official HITRAN2008 release were found to be erroneous. This situation has now been fixed. In addition, the 13C12CH6 isotopologue had not been added to the official release of HITRAN2008 despite the text in the HITRAN paper. This new isotopologue has now been included. The data can be downloaded here either in ASCII:   27_hit09.par or compressed format:   27_hit09.zip These files should be used as a complete replacement of the 2008 ethane linelist.

Update for OCS (Carbonyl sulfide)

It was found that due to a programming error some of the air- and self-broadening halfwidths for all isotopologues of OCS were in error by as much as 50%. It was also found in the process that there is a typo in the b3 coefficient for the O2-broadening Padé approximant given in M.A. Koshelev and M.Y. Tretyakov, "Collisional broadening and shifting of OCS rotational spectrum lines," JQSRT 110, 118-128 (2009). This b3 coefficient needs to be divided by 10. These mistakes have now been fixed, yielding much improved broadening parameters. We thank Maxim Koshelev from the Institute of Applied Physics (Nizhny Novgorod, Russia) for pointing out these errors. While performing this correction, the line positions and intensities in the pure rotational band for all of the HITRAN OCS isotopologues were updated using parameters from the Cologne Database for Molecular Spectroscopy (CDMS). The intensities were converted using the procedure described in the appendix of the HITRAN2008 paper, which includes scaling of the partition functions. The data can be downloaded here either in ASCII:   19_hit09.par or compressed format:   19_hit09.zip These files should be used as a complete replacement of the 2008 carbonyl sulfide linelist.

Update for H2O (Water vapor)

An error was discovered in the transcription of the intensities of HDO line parameters above 11500 cm-1. They were a factor of 10 too large in the 2008 release of HITRAN, and have now been corrected here. Thanks to B.A. Voronin of the Institute of Atmospheric Optics, Tomsk Russia, for pointing this error out to us. The data can be downloaded here either in ASCII:   01_hit09.par or compressed format:   01_hit09.zip These files should be used as a complete replacement of the 2008 water vapor linelist.
