Data Availability And Requirements Relevant For The Ariel Space Mission And Other Exoplanet Atmosphere Applications
Comparison of 12CH4 cross-sections at 296 K in the far and mid-infrared regions for different databases: MeCaSDa (Ba et al. 2013), TheoReTs (Rey et al. 2016b), the ExoMol MM line list (Yurchenko et al. 2024a), HITRAN2020 (Gordon et al. 2022) and HITEMP (Hargreaves et al. 2020). — astro-ph.IM

The goal of this white paper is to provide a snapshot of the data availability and data needs primarily for the Ariel space mission, but also for related atmospheric studies of exoplanets and brown dwarfs.

It covers the following data-related topics: molecular and atomic line lists, line profiles, computed cross-sections and opacities, collision-induced absorption and other continuum data, optical properties of aerosols and surfaces, atmospheric chemistry, UV photodissociation and photoabsorption cross-sections, and standards in the description and format of such data.

These data aspects are discussed by addressing the following questions for each topic, based on the experience of the “data-provider” and “data-user” communities: (1) what are the types and sources of currently available data, (2) what work is currently in progress, and (3) what are the current and anticipated data needs.

We present a GitHub platform for Ariel-related data, with the goal to provide a go-to place for both data-users and data-providers, for the users to make requests for their data needs and for the data-providers to link to their available data. Our aim throughout the paper is to provide practical information on existing sources of data whether in databases, theoretical, or literature sources.
