HITRAN is an acronym for high-resolution transmission molecular absorption database. HITRAN is a compilation of spectroscopic parameters that a variety of computer codes use to predict and simulate the transmission and emission of light in the atmosphere.
Dear Colleagues,
The data on this website corresponds to the HITRAN2020 edition of the database. The HITRAN2020paper describing the new edition is available in Open Access

==> Note that we are constantly making ongoing improvements and additions to many molecular bands. Updates, improvements, and corrections to the edition are posted in the "Database Updates" panel located on the home page of the HITRAN website. When citing the database, it is recommended to indicate if an updated version of the HITRAN2020 edition was used.
Please e-mail us (info@hitran.org) a summary of any serious problems you encounter (or successes or suggestions).

A review article describing the history of the HITRAN database by Larry Rothman was just published in Nature Reviews Physics. https://doi.org/10.1038/s42254-021-00309-2

The HITEMP database has been expanded to include methane. The data is available through the HITEMP section of the website (https://hitran.org/hitemp/), with a python tool for extracting the compressed file. Further details are described by Hargreaves et al. (2020) (doi:10.3847/1538-4365/ab7a1a).

The HITRAN support e-mail has been established and our team is ready for questions.

It was found that in the process of combining different line lists of ozone for HITRAN2020, the lines of the principal isotopologues of ozone in the 850-980 cm-1 spectral region were accidentally omitted. These lines are now restored. Although most of these transitions are relatively weak, they are still important in remote sensing applications. We thank Norbert Glatthor (KIT) for pointing out this issue.
