The ACE infrared solar atlas (Hase et al., 2010) is a model atmosphere for solar-type stars; an improved solar atlas is currently being prepared by F. Hase. The solar atlas has also been used to assign infrared spectra of atomic lines; for example, Peterson and Kurucz (2022) assigned new Fe lines. The solar occultation geometry of ACE is similar to the geometry used for transit spectroscopy of exoplanets. The ACE atmospheric atlases (Hughes et al. 2014) therefore serve as a model for Earth-like exoplanet atmospheres. Doshi et al. (2022) used ACE spectra of clouds to determine their effect on exoplanet transit spectra observed with the James Webb Space Telescope.
In recent work, ACE’s solar atlas was used to generate an updated fluorescence emission model of CO+ for cometary science (Bromley, et al., 2024), for the detection of carbon dioxide and hydrogen peroxide on the surface of Charon (Protopapa et al., 2024), and a study into Pluto’s atmosphere gas and haze composition (Lellouch et al., 2025). Work also started on generating a new solar atlas that used more solar spectra in the average and improved the alignment of the individual spectra prior to including them in the average (paper in preparation).
