Light Penetration into the Canopy of Terrestrial Ecosystems
The description of the penetration of radiation into a vegetation canopy would appear to be a simple task. In essence, radiation approaches an object and is variously reflected, absorbed, and transmitted. Although these are concepts in photophysics which it should be possible to describe in simple and easily quantifiable terms, natural radiation is a complex phenomenon which varies in quantity, quality, and time. The vegetation canopy is also a complex object which varies not only in the spectral characteristics of its elements, but also spatially and temporally.
