N 95-33747 Evaluation of the Photochemical Reflectance Index in Aviris Imagery

In this paper, we evaluate the potential for extracting the "photochemical reflectance index" (PRI; previously called the "physiological reflectance index") from AVIRIS data. This index, which is derived from narrow-band reflectance at 531 and 570 nm, has proven to be a useful indicator of photosynthetic function at the leaf and canopy scales (Gamon and… CONTINUE READING
