The HITRAN2020 database will be release publicly in the coming months. It is a coordinated effort of experimentalists, theoreticians, atmospheric and planetary scientists who measure, calculate and validate the HITRAN data.
The lists for many of the HITRAN molecules in the line-by-line section (and several additional ones have been added) were updated in comparison with the previous compilation HITRAN2016 (Gordon et al., 2017). 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, CH3F, GeH4, CS2, CH3I, and NF3) were also added to HITRAN. Many new vibrational bands were added to the database, extending the spectral coverage and completeness of the line lists. 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 (Tan et al., 2019); etc. A major update of collision-induced absorption sets (Karman et al., 2019), is also one of the highlights of the new edition.
The HITRAN2020 edition will continue taking advantage of the modern database structure and interface available at www.hitran.org (Hill et al., 2016) and the HITRAN Application Programming Interface (Kochanov et al., 2016). The functionality of both tools has been extended for the new edition.
This presentation will provide a brief overview of the HITRAN2020 edition with an emphasis on greenhouse gases and oxygen.
