For a spherical planet, The bond albedo of the Earth is roughly 0.38. Albedo, Geometric Albedo, Phase IntegralThe geometric albedo upper limits which we derive in this work for WASP-18 b, WASP-36 b, WASP-43 b, WASP-50 b, and WASP-51 b all lie below 0.45.

The geometric albedo of an astronomical body is the ratio of its actual brightness at zero phase angle (i.e. as seen from the light source) to that of an idealized flat, fully reflecting, diffusively scattering disk with the same cross-section.. Diffuse scattering implies that radiation is reflected isotropically with no memory of the location of the incident light source.The physical and thermal properties of the asteroid are relevant for establishing the scientific mission goals and also important in the context of near-Earth object studies in general. Aims: Our goal was to derive key physical parameters such as shape, spin-vector, size, geometric albedo, and surface properties of 162173 (1999 JU3). Methods ... There are multiple types and definitions of albedo. In the case of large asteroid surveys, the geometric albedo in the visible, p v, is determined on the basis of mid-infrared observations coupled with a thermal model and visible observations (Lebofsky et al., 1986). The geometric albedo is defined as the brightness ratio between the reflectedAs the Arctic warms (e.g., due to the increase of greenhouse gases and/or atmospheric circulation changes), the retreat of snow and ice together with the associated feedbacks is known to be an important reason for Arctic amplification of the warming (8–15).Reduction of surface snow and ice results in a decrease of surface albedo, …

In combination of our result with infrared photometry, the geometric albedo is updated to be 0.05 (Mueller et al. in preparation), which is typical to but slightly smaller than the average of C-type asteroids in main-belt. We found that the magnitude-phase angle relation has a linear behavior in a wide range of the phase angles (5-80For metallic surfaces, we vary F0 by linearly interpolating between the original F0 and the albedo value given the metallic property. Given \(F\), the remaining terms to calculate are the normal distribution function \(D\) and the geometry function \(G\). In a direct PBR lighting shader their code equivalents are:In more technical treatments of albedo, such as that of de Pater and Lissauer, a distinction is made between "bond albedo" and "geometric albedo", the numbers quoted above being geometric albedos. The geometric albedo is defined as the amount of radiation relative to that from a flat Lambertian surface which is an ideal reflector at all ... ….

We have used the PPS ultraviolet (0.25 μm) and infrared (0.75 μm) filter data and the ISS violet (0.41 μm) and green (0.56 μm) filter data to produce geometric ...

eter form its infrared flux. The visible geometric albedo of the body can then be derived. These albedos vary across the belt, but tend to be fairly homogeneous within an asteroid family [5]. Motivated by this, we predict the albedo of asteroids as a function of their proper elements across the entire main belt. We predictThe reflected radiation is penetrating through the windows, and therefore can increase the indoor temperature. The effect is however very much dependent on the street geometry, albedo and amount of glazing. This indicates that using one adaptation strategy on all locations might give different results, dependent on the local geometry.The geometric albedo of an astronomical body is the ratio of its actual brightness at zero phase angle (i.e. as seen from the light source) to that of an idealized flat, fully reflecting, diffusively scattering disk with the same cross-section.. Diffuse scattering implies that radiation is reflected isotropically with no memory of the location of the incident light source.

Wikipedia points out in this article about Bond Albedo; that Bond Albedo sometimes can be greater than Geometric Albedo, which apparently is the case with Venus and Mars.Validation of satellite albedo products relies on reference value on the coarse pixel scale which is acquired by independent means. In previous research, reference value was generally obtained within the nominal spatial extent of the validation pixel from in situ observations or high spatial resolution airborne/spaceborne albedo references. Nevertheless, the signal of the validation pixel may ...
