HITRAN and HITEMP:new additions and features to aid planetary research

The work on the new editions of the HITRAN and HITEMP molecular spectroscopic databases is well underway with many new or improved data already available through the HITRAN website www.hitran.org . These data will update the current editions, HITRAN2016 [1] and HITEMP2010 [2]. We have added, revised, and improved many transitions and bands of molecular species and their isotopologues. For instance, for HITEMP the line list of NO was recently improved and expanded, while high-temperature line lists for the N₂O and NO₂ molecules added for the first time [3]. Also, the amount of parameters has been significantly increased, and now incorporate broadening by H₂O, He, H₂ and CO₂ that are dominant in different planetary atmospheres [4,5]. Furthermore, the section of the database for the collision-induced absorption has recently been substantially improved and extended [6]. In addition, HAPI (HITRAN Application Programing Interface) [7], which is a set of Python libraries designed to work with HITRAN and HITEMP data, is being updated by substantially increasing the speed of calculations and additional functionalities. This poster will provide a summary of these updates, emphasizing details of the most important updates, additions and drastic improvements.
