摘要: The purpose of this paper is to present a method for using remote measurements estimate vegetation fraction, surface energy fluxes and the root zone soil water contents partial canopies. primary tools are boundary layer model with substrate components two image products: variation radiometric temperature vs. normalized difference index (NDVI), standard deviation temperature. based on determining: (1) asymptotic values temperatures sunlit bare dense vegetation; (2) relationship between NDVI temperature, which we call axis variation. illustrated aircraft made at Lubbon during French HAPEX field experiment (1986).
