Spectral signatures of vegetation and their relevance for remote biosignature detection
The vegetation red edge (VRE) - a sharp increase in reflectance between approximately 700 and 750 nm arising from chlorophyll absorption of visible light and strong near-infrared scattering within leaf tissues - represents the most extensively studied surface biosignature for remote detection of photosynthetic life. Th...
