Bond albedo, defined as the fraction of the total incident solar radiation reflected by a planet back to space, is a measure of the planet’s energy balance. (It is so named for the American astronomer George P. Bond, who in 1861 published a comparison of the brightness of the Sun, the Moon, and Jupiter.)Bond albedo is a measure of a planet’s energy balance, defined as the proportion of total incident solar radiation reflected in space by the globe. Because Bond albedo is defined throughout the complete range of wavelengths, its value is determined by the spectrum of incident light.You’ve likely heard of savings bonds, but what exactly are they and how do they work? Join us as we answer these questions and more. We’ll give you the scoop on different types of savings bonds, where to get them, and whether or not they ar...We propose a formula for computing the average planetary surface temperatures based solely on the solar irradiance and the bond albedo.

The lunar average Bond albedo (at normal solar incidence) A is 0.12 (Vasavada et al. 2012). This is in agreement with the mean value of 0.122 found by Saari & Shorthill (1972). Vasavada et al. (2012) derived a mean albedo of 0.07 for mare and 0.16 for highlandsurfaces from measurements taken by the Diviner Lunar Radio Experiment.The colder the surface temperature is, the thicker the clouds are, and the higher the Bond albedo is. We also evidence that the relative abundances of CO 2 and H 2 O in the atmosphere strongly impact the Bond albedo. The Bond albedo is higher for atmospheres dominated by the CO 2, better Rayleigh scatterer than H 2 O. Finally, we provide the ...The albedo is used to compute 133P's temperature distribution, which shows significant seasonal variation, especially polar regions, ranging from $\sim40$ to $\sim200$ K. Based on current activity observations, the maximum water gas production rate is estimated to be $\sim1.4\times10^{23}\rm~s^{-1}$, being far weaker than $\sim10^{26}\rm~s^{-1 ...Albedo values range from 0 (pitch black) to 1 (perfect reflector).

Our work shows a connection between very high albedo (near unity) and planetary activity, a result that suggests the KBO Eris may be currently active.The Bond albedo is a measure of the energy balance of a body: it is the ratio of the power at a specific wavelength on a body that is scattered back out into space. When integrated over the entire electromagnetic spectrum, it is the bolometric Bond albedo. More formally, the Bond albedo is equal to p, the geometric albedo, times q, the phase ...February 24, 2022. On this part of Mars there is an extensive surface brightness (albedo) boundary. One hypothesis is that this boundary marks a shoreline, from a time long ago when liquid water could have been stable on the surface of Mars. With the resolution of HiRISE we can see that the reason one side of the boundary is darker than the ...1. We use the method of Donohoe & Battisti ( 2011) to calculate the contributions of the surface and the atmosphere to the Bond albedo of each planet and thus partition the ensemble into planets whose albedos are dominated by clouds versus planets with significant contributions of surface scattering to albedo. 2.Maps of the variation in bolometric Bond albedo and thermal inertia across Rhea and Dione have been produced using various day and nighttime observations, taken by Cassini's Composite Infrared Spectrometer (CIRS). The albedo maps show the same trend that has been previously observed on these satellites from reflected sunlight and thermal observations: a higher albedo on their leading hemispheres.The model is parameterized by the planet's Bond albedo, the ratio of radiative to advective timescales and a greenhouse-warming factor 25,26.
