// Actual earth average albedo is about 0.30 (and varies with time.) // (This is the Bond albedo, not the geometric albedo.) albedo = 0.30 // Where earthEta is the emissivity of the earth. For a blackbody this is 1, // for most materials, around 0.95, but for clouds it's about 0.5.This phenomenon is not to be confused with albedo, which is really a measure of the ability of a surface to scatter light, turning it white. The prime example of this is clouds, which scatter light very effectively both here and on Venus (Venus has a bond albedo of .75, which is quite high, due to clouds). But clouds can hardly bounce light ...This young girl soon forged an unbreakable bond with everyone in the Knights of Favonius.

What is Albedo? Ice reflects 50% to 60% of incoming solar heat. Albedo is part of the energy from the sunlight that casts back into the atmosphere. These rays have a significant effect on our climate. When the albedo rises, the universe reflects light more and consequently, higher levels of radiation are sent back to space so the Earth cools down.Saturn Fact Sheet . Saturn.

Normal albedo is a measure of a surface's brightness when illuminated and observed vertically, while bond albedo is defined as the fraction of total solar light reflected back to space and is a measure of a planet's energy balance. The value of bond is defined over the entire ...Jupiter's albedo is 52 percent.

The predicted Bond albedo of a class I planet around a star like the Sun is 0.57, compared with a value of 0.343 for Jupiter and 0.342 for Saturn. The discrepancy can be partially accounted for by taking into account non-equilibrium condensates such as tholin or phosphorus , which are responsible for the coloured clouds in the Jovian atmosphere ...The relationship between the BBD and the OVIRS bond albedo and OTES thermal inertia are also shown in Fig. 3. The daytime BBD has a strong positive correlation (r = 0.64 (0.03)) to albedo and a moderate correlation to thermal inertia (r = 0.51 (0.03)).The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength.

But besides that which is reflected, some incoming sunlight is also absorbed by both atmospheres, although ...The wavelength and spherically integrated albedo, or Bond albedo, has typically been cited as between 0.7 and 0.82 (Colin 1983). Yet, recent photometry of Venus at extended phase angles between 2 and 179° indicate a Bond albedo of 0.90 (Mallama et al., 2006).

The Bond albedo, named after the American astronomer George Phillips Bond (1825-1865), who originally proposed it, is the fraction of power in the total electromagnetic radiation incident on an astronomical body that is scattered back out into space.Albedo is usually differentiated into two general types: normal albedo and Bond albedo.

The normal albedo of snow, for example, is nearly 1.0, whereas that of charcoal is about 0.04. ...

A New Bond Albedo for Performing Orbital Debris Brightness to Size Transformations We have developed a technique for estimating the intrinsic size distribution of orbital debris objects via optical measurements alone. The process is predicated on the empirically observed power-law size distribution of debris (as indicated by radar RCS measurements) and the log-normal probability distribution ...Bond albedo for extrasolar planets had been estimated from their visible luminosities at secondary eclipse (i.e., from their geometric albedos A g) and by balancing the flux radiated in the infrared (Schwartz & Cowan 2015).

Regarding to the Bond albedo, we find the large difference between our study (0.503 ± 0.012) and the previous result (0.343 ± 0.032) by Hanel et al. 24. The Bond albedo is further determined by two factors: geometric albedo and phase integral.The phase coefficient between phase angles of 0.8° and 42° of 0.042+/-0.004 mag/deg indicates that the phase integral does not exceed 0.3 and that the Bond Albedo is less than 0.02.

You need to decide the percent of starlight that your planet reflects back into space. Since this is a percent, you should choose a number between 0 (no starlight reflected) and 100 (all of the starlight reflected). You do not need to enter the percent sign. remi martin The bond albedo of an object is simply the average amount of total light that is scattered in any direction by the object.

The rings particles demonstrate a steep opposition surge—an increase of the albedo when the phase angle is close to zero. This means that their albedo is much lower when they are observed slightly off the opposition.
