    the surface temperature, evaporates water, melts and sublimates snow and ice, and energizes the turbulent heat exchange between the surface and the lowest layer of the atmosphere. The surface albedo is a key ingredient in the remote sensing of surface and atmospheric properties from space. The spectral and. The atmospheric correction algorithm used to retrieve the surface reflectance relies on a look-up table (LUT) approach. The LUT contains forward radiative transfer calculations from a Gauss-Seidel iteration code to compute at-satellite radiance for a set of assumed surface reflectance values and a variety of atmospheric conditions.

    A theoretical investigation has been made of surface polariton reflection and radiation at the end face of a metal slab. Dielectric materials of dielectric constants ε d and ε ′ d lie above and beyond the end of the metal slab, respectively. Energy transmission and reflection coefficients have been calculated for a surface polariton incident on the end face of the metal slab for various. Surface Reflectance is ratio of the amount light not absorbed by a surface to the amount of light striking the surface. Albedo is a measure of energy and Surface Reflectance is a property of a material. Solar radiation times the percentage that gets through the atmosphere and strikes the surface times the Surface Reflectance ratio equals Albedo.

    Approximating Landsat Surface Reflectance Previous White Papers have described the concept of Top of Atmosphere (TOA) Reflectance. TOA reflectance is a unitless number that can be computed from satellite spectral radiance, the earth-sun distance in astronomical units, the mean solar exoatmospheric irradiance and the solar zenith angle. The thermal fluctuations in surface electric fields are determined, and the frequency-dependent relaxation rates of the surface polaritons are derived; the main concern is with polaritons which are mixtures of photons with optic phonons, but the photon-plasmon type of polariton is also discussed as a special case.

Surface polariton resonances and reflectance on a bigrating by John Gary Melendez Download PDF EPUB FB2

Surface plasmon polaritons (SPPs) are electromagnetic waves that travel along a metal–dielectric or metal–air interface, practically in the infrared or term "surface plasmon polariton" explains that the wave involves both charge motion in the metal ("surface plasmon") and electromagnetic waves in the air or dielectric ("polariton").

Diffraction of light by a bigrating: Surface polariton resonances and electric field enhancements The amplitudes of the diffracted spectral orders are calculated for a sinusoidal bigrating and for a square lattice of hemiellipsoids on a flat surface, for Ag.

The enhancement of the electric field on and near the surface is calculated and is. Surface resonances: Effective polarizability of the tip and field enhancement We begin our study with the analysis of the simplest structures that either supporting or not supporting resonances (Fig.

Reflectance of the surface of a material is its effectiveness in reflecting radiant is the fraction of incident electromagnetic power that is reflected at an interface.

Qu, in Comprehensive Remote Sensing, Definition of Reflectance Quantities. Surface reflectance (ρ) is defined as the fraction of incoming solar radiation that is reflected from Earth’s surface for specific incident or viewing cases (directional, conical, and hemispherical cases).The reflectance quantities for different incident and viewing geometries can be clearly defined.

Spectral Reflectance. Different surface features reflect and absorb the sun's electromagnetic radiation in different ways. The reflectance properties of an object depend on the material and its physical and chemical state, the surface roughness as well as the angle of the sunlight.

The reflectance of a material also varies with the wavelength. Here the depth argument of "in air" indicates that is evaluated using the water-leaving radiance and in the air, just above the water surface.

The remote-sensing reflectance is a measure of how much of the downwelling radiance that is incident onto the water surface in any direction is eventually returned through the surface into a small solid angle centered on a particular direction, as.

There is an alternative, completely different method of measuring reflectance. Jupp [4] indicates that reflectance may be determined by the ratio of reflected to incident illumi nances: ρ = Er Ei (3) where: Er is the reflected illuminance in lux Ei is the incident illuminance in lux.

Zayats, I. Smolyaninov, Journal of Optics A: Pure and Applied Optics 5, S - Surface reflectance is a property of the surface (or ground) itself, i.e. in this case the sea surface. It is determined using Fresnel's Equations and Snell's Law, both functions of the relative.

For many applications, radiance, reflectance, and apparent reflectance can be used interchangibly. However, since reflectance is a property of the target material itself, you will get the most reliable (and repeatable) vegetation index values using reflectance.
