1Scale effect of Planck's law over nonisothermal blackbody surface显示文摘Many physical laws, principles, models, measurement methods, etc., are applicable only to either a point on surface or a homogeneous surface. However, remote sensing deals with pixels which may range from meters to kilometers. Therefore scale effects of these laws and measurements are inevitable problems which must be faced. As an example, the spatial scale effect of Planck Law over nonisothermal blackbody surface is considered.李小文 王锦地 A. H. Strahler 1999Science China(Technological Sciences)1999,42,6:12

3基本颗粒构成的粗糙表面二向性反射——相互遮蔽效应的几何光学模型显示文摘当前从遥感图像上借以识别地物的仍然是它的波谱特征。仅仅凭借这一特征,还不能充分利用遥感图象所包含的信息。从经验中知道,物体的阴影对于识别其三维结构有非常重要的作用,尤其在不同的入照和观测方向上,从观察到的阴影变化可以推断出物体的三维结构特征。本文着重讨论构成粗糙表面的基本颗粒之间相互遮蔽对二向性反射的影响。1 二向性反射分布函数(BRDF)及其几何-光学模型地面物体的反射是个非常复杂的物理现像,它是入射光天顶角θ_i和方位角φ_i。李小文 A.И.Strahler 朱启疆 朱重光 1993科学通报1993,38,1:4
4A kernel-driven model of effective directional emissivity for non-isothermal surfaces显示文摘Land surface temperature (LST) is a key geophysical parameter that reflects the combined effects of land surface energy and radiation balance. Remote sensing of LST, however, requires understanding the directional patterns of thermal emission from heterogeneous land surfaces. Recently, semi-empirical, linear, kernel-driven models have been successfully used to describe observed directional patterns of land surface reflectance. Following a similar methodology and based on a recent model of the physics of directional thermal emission from heterogeneous land surfaces, a kernel-driven semi-empirical model for thermal emission is developed using three kernels: (i) an isotropic kernel, corresponding to the gray-body component in a heterogeneous pixel; (ii) a two-layer canopy kernel, derived from a previous conceptual model; and (iii) a geometric optical kernel that accounts for the fact that sunlit parts are hotter than shaded parts in a pixel. The three-kernel model fits 1997 airborne directional thermal brightness data over Avignon, France, very well.Mark FRIEDL Alan STRAHLER 2002Progress in Natural Science:Materials International2002,12,8:4
