Modeling Disk-Averaged Spectra of Earth
April 6, 2006 / Posted by: Shige Abe
To assess the detectability of planetary characteristics in disk-averaged spectra, the NAI Virtual Planetary Laboratory Team has developed a spatially and spectrally resolved model of the Earth. Using infrared observations of the Earth taken by existing instruments orbiting Mars, and ground-based observations of earthshine, the model has been validated, and indicates that several atmospheric species can be identified. Models such as this one will help analyze disk averaged spectra as returned from upcoming NASA and ESA extra-solar planet detection and characterization missions. They published their results in the February issue of Astrobiology.
