Biomarkers in disk-averaged near-UV to near-IR Earth spectra using Earthshine observations

Year: 2006

Type: article

Abstract: Context.The detection of exolife is one of the goals of very ambitious future space missions or extremely large ground-based telescopes that aim to take direct images of Earth-like planets. While associations of simple molecules present in the planet's atmosphere (O2, O3, CO2 etc.) have been identified as possible global biomarkers, we analyse here the detectability of vegetation on a global scale on Earth's surface.
