State of the art, first principles quantum mechanical methods will be used to computehigh accuracy transition intensities, for both the infrared (IR) and ultraviolet (UV)regions of the spectrum of ozone. For the infrared region, existing methodology ofcomputing high accuracy dipole moment surfaces will be employed. These methodshave already been used successfully for water and CO2 to calculate high accuracytransition intensities. Complete line lists will be obtained by combining accurateintensities with measured transition frequencies. New methodologies will bedeveloped and implemented in computer programs to compute intensities forelectronic transitions in the UV region. The results of this study will be important for arange of atmospheric studies, such as self-consistency of ozone concentrationretrievals in remote sensing techniques, and possible detections of ozone in exoplanetaryatmospheres. The distribution of ozone line lists will involve making themavailable online on databases, such as HITRAN and ExoMol, dedicated to thecompilation of spectroscopic parameters. HITRAN is the standard for such datacompilations for atmospheric studies and will be independently evaluating the resultsof this study.
