possibility of estimating the concentration of individual
photosynthetic pigments within vegetation from reflectance
spectra offers great promise for the use of remote sensing to
assess physiological status, species type and productivity. This
study evaluates a number of spectral indices for estimating
pigment concentrations at the leaf scale, using samples from
deciduous trees at various stages of senescence. Two new indices
(PSSR and PSND) are developed which have advantages over
previous techniques. The optimal individual wavebands for
pigment estimation are identified empirically as 680 nm for
chlorophyll a, 635 nm for chlorophyll b and 470 nm for the
carotenoids. These wavebands are justified theoretically and are
shown to improve the performance of many of t
