The radiative transfer capabilities of the PHOENIX code have been applied to the case of Earth-like planets. This model is now able to produce averaged spectra of terrestrial planets from the UV to the far infrared, including both reflection of the stellar light and proper thermal emission of the planet. By degrading the resolution of the computed spectra and adding some observational noise, we can simulate observations made with future space observatories (Darwin, TPF-C) or with Extremely Large Telescopes (ELT) from the ground, through the Earth atmosphere. We can thus quantify the instrumental performance (resolution sensitivity) required to detect given spectral features: Rayleigh scattering by an atmosphere, atmospheric species like H2O, CO2, O2, O3, CH4, or surface properties (like the vegetation red-edge).
