Abstract
The HITRAN2020 database will be publicly released this year. It is a coordinated effort of experimentalists, theoreticians, atmospheric and planetary scientists who measure, calculate and validate the HITRAN data. The lists for most of the HITRAN molecules in the line-by-line section were updated in comparison with the previous compilation HITRAN2016\footnote{Gordon et al., (2017). JQSRT. 203, 3–69.}. The extent of the updates ranges from updating a few lines of certain molecules to complete replacements of the lists and introducing additional isotopologues. Six new molecules (SO, CH$_{3}$F, GeH$_{4}$, CS$_{2}$, CH$_{3}$I, and NF$_{3}$) were also added to HITRAN. In addition, the accuracy of the parameters for major atmospheric absorbers has been increased, often featuring sub-percent uncertainties. The number of parameters was also increased significantly, now incorporating, for instance, non-Voigt line profiles for many gases; broadening by water vapor\footnote{Tan et al., (2019) J. Geophys. Res. Atmos. 2019JD030929.}; update of collision-induced absorption sets\footnote{Karman et al., (2019) Icarus 328, 160–175.}. The new edition will continue taking advantage of the modern structure and interface available at www.hitran.org and the HITRAN Application Programming Interface\footnote{Kochanov et al., ( 2016) JQSRT. 177, 15–30.}. Their functionality has been extended for the new edition. This talk will provide a brief overview of HITRAN2020\footnote{This work is supported by NASA.} and its main improvements with respect to the previous edition.
