Vegetation signature in the observed globally-integrated spectrum of Earth : Modeling the red-edge strength using simultaneous cloud data and application for extrasolar planets

Abstract

A series of missions will be launched over the next few decades that will be designed to detect and characterize extrasolar planets around nearby stars. These missions will search for habitable environments and signs of life (biosignatures) in planetary spectra. The vegetation’s “red edge”, an intensity bump in the Earth’s spectrum near 700 nm when sunlight… (More)
