Simulating the relationship between thermal emissivity and the normalized difference vegetation index

Abstract

An experimental relation between the thermal emissivity and the Normalized Difference Vegetation Index of vegetation canopies has been found by van de Griend and Owe. This relationship is investigated by means of a radiative transfer model. The relationship was highly sensitive to soil and leaf emissivities, canopy structure, optical properties of leaves and soil in the solar domain and Sun geometry, but insensitive to viewing geometry. © 1995 Taylor & Francis Group, LLC.
