Journal ArticleDOI

Crystal B. Schaaf,Feng Gao,Alan H. Strahler,Wolfgang Lucht,Xiaowen Li,Trevor Tsang,Nicholas C. Strugnell,Xiaoyang Zhang,Yufang Jin,Jan-Peter Muller,Philip Lewis,M. J. Barnsley,P. Hobson,Mathias Disney,Gareth Roberts,Michael Dunderdale,Christopher N.H. Doll,Robert P. d'Entremont,Baoxin Hu,Shunlin Liang,Jeffrey L. Privette,David P. Roy +21 more
TL;DR: The MODIS BRDF/Albedo algorithm makes use of a semi-empirical kernel-driven bidirectional reflectance model and multidate, multispectral data to provide global 1-km gridded and tiled products of the land surface every 16 days.
Journal ArticleDOI
Geometric-optical bidirectional reflectance modeling of the discrete crown vegetation canopy: effect of crown shape and mutual shadowing
Xiaowen Li,Alan H. Strahler +1 more
TL;DR: In the case where a vegetation cover can be regarded as a collection of individual, discrete plant crowns, the geometric-optical effects of the shadows that the crowns cast on the background and on one another strongly condition the brightness of the vegetation cover as seen from a given viewpoint in the hemisphere.
Journal ArticleDOI
On the derivation of kernels for kernel-driven models of bidirectional reflectance
TL;DR: In this paper, a new approximation to Ross' (1981) radiative transfer theory for small values of leaf area index (LAI) and two new approximations to Li and Strahler's (1992) geometric-optical mutual shadowing model are derived.
Journal ArticleDOI
Geometric-Optical Modeling of a Conifer Forest Canopy
Xiaowen Li,Alan H. Strahler +1 more
TL;DR: In this paper, a geometric-optical forest canopy model that treats conifers as cones casting shadows on a contrasting background is proposed to explain the major portion of the variance in a remotely sensed image of a forest stand.
Journal ArticleDOI
Geometric-Optical Bidirectional Reflectance Modeling of a Conifer Forest Canopy
Xiaowen Li,Alan H. Strahler +1 more
TL;DR: A geometric-optical forest canopy model that treats conifers as cones casting shadows on a contrasting background explains the major anisotropies in bidirectional reflectance measurements of a conifer forest canopy as discussed by the authors.
