Difference between Albedo and Surface Reflectance

2018-10-19 04:58:52

Can anyone tell me what is the difference between Albedo and surface reflectance? I know for sure that they are not the same. Any links / comments are most welcome.

Albedo is a measure of the diffuse reflectivity of a surface, as opposed to specular reflectivity such as that of glass or water.

Albedo is the percentage of solar energy striking a surface that is reflected away from the earth.

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.

A perfect mirror at night produces zero Albedo.

I agree with @blah238 here is more information

Albedo is the percentage of solar radiation reflected by an

object.

    Albedo is the percentage of solar radiation reflected by an

    object.

    Reflectivity is the capacity of an object to reflect solar radiation.

    It is described as a function of radiation wavelength and is

    determined by the physical composition of the object.

    Relation of reflectivity to albedo

    Albedo is the integrated product of incident solar radiation spectral

    composition and the spectral reflectivity of the object. Outside

    the atmosphere, solar radiation spectral composition is relatively

    constant, peaking at about 0.5µm, decreasing rapidly at shorter

    wavelengths to small amounts at 0.2µm, and decreasing less rapidly

    at longer wavelengths to small amounts at about 4.0µm.

    The atmosphere selectively absorbs and scatters solar radiation.

    As a result, at the Earth’s surface the spectral composition

    of solar radiation varies significantly as a function of atmospheric

    conditions (e.g. clouds, water vapor, and dust) and solar
