The newly selected Venus missions EnVISION and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) by ESA and NASA offer new opportunities for studying Venus but will also contribute to furthering our knowledge of Venus as an exoplanet. Hot, rocky planets are favoured exoplanet targets due to generally more frequent transits than cooler Earth-like objects. In our work presented here, we simulate Venus as an exoplanet using our coupled climate-photochemical model 1D-TERRA. In the simulations, we vary stellar, orbital, planetary and atmospheric parameters and study the effect of these parameters upon atmospheric composition, climate and spectral detectability with forthcoming missions.
