Earthshine observations and the detection of vegetation on extrasolar planets

Abstract To prepare future observations of terrestrial planets and the detection of life, we search for life on the planet Earth seen as a point source.

Description
Summary:Abstract To prepare future observations of terrestrial planets and the detection of life, we search for life on the planet Earth seen as a point source. Observations of Earthshine is a convenient way to see Earth as a remote planet. The vegetation reflectance spectrum presents a sharp edge in the near infrared: the Vegetation Red Edge. Observational programs in progress are described, particularly our observations at the Concordia station in Antarctica.
