A concept more closely related to the variations in the perceived brightness of planets due to variations in surface properties is the geometric albedo, or sometimes called the visual geometric albedo when referring specifically to the band of visible wavelengths. Geometric albedo is determined by comparing the light received from an entire ...For a sphere with a Lambertian surface, the geometric albedo is 2/3 of the surface reflectance (Dlugach and Yanovitskij, 1974, Sobolev, 1975, Cahoy et al., 2010). In our results, the geometric albedo computed for zero haze approaches a constant value that is half this expected result.

Land surface albedo—the fraction of radiative flux reflected by a surface to the atmosphere —is a critical variable in estimating the global surface energy budget (Dickinson, 1983, Liang et al., 2019, Schaaf et al., 2002).It is one of the essential climate variables that reflect the variations, patterns, and drivers of the Earth's climate by regulating the biophysical ...The influence of urban geometry on urban albedo and street surface temperature was studied in three different scenarios. Table 1 presents the morphometric parameters of the three study scenarios. First, the impact of building density is examined in Scenario A, which varies the plan area index while keeping building height constant (H / L = 1).Once the diameter is known, a comparison with visible light observations can be used to find the visible geometric albedo of the body.
