Paper Abstract

An analysis, based on the inversion of a simple non-linear model of the ground reflectance, was conducted on several AVIRIS scenes. The scenes were acquired during the MAC EUROPE 91 campaign on the 5th and 22nd of July, over two test sites (Black Forest and Freiburg). The model consists in a linear mixing of the soil reflectance and a green vegetation reflectance described with a Kubelka-Munk formula containing the chlorophyll and water specific absorption coefficients. Its inversion provides a Green Vegetation Fraction of the pixel and two parameters related respectively to chlorophyll and water. The model can then be used to evaluate the magnitude of the 1.7 micrometers absorption feature which is thought to be a signature of the vegetation biochemical components. The spatial and temporal variability of this feature over the scenes is commented.17
