Albedo (/ æ l ˈ b iː d oʊ / al-BEE-doh; from Latin albedo 'whiteness') is the fraction of sunlight that is diffusely reflected by a body. It is measured on a scale from 0 (corresponding to a black body that absorbs all incident radiation) to 1 (corresponding to a body that reflects all incident radiation).
A 1934 map showing some of Mercury's albedo features. This is a list of the albedo features of the planet Mercury as seen by early telescopic observation.. Early telescopic observations of Mercury were based on the assumption that Mercury keeps one of its faces permanently turned toward the Sun, through the mechanism of tidal locking.
colour (slightly enhanced) represents the hue of the object; no albedo differences are currently displayed, in spite of the graph's title! the size of a sphere illustrates the object's size relative to others. for a few large objects, the diameter drawn represents the current estimates (for known albedos)
In astronomy, the geometric albedo of a celestial body is the ratio of its actual brightness as seen from the light source (i.e. at zero phase angle) to that of an idealized flat, fully reflecting, diffusively scattering disk with the same cross-section.
The first albedo feature ever seen on another planet was Syrtis Major Planum on Mars in the 17th century. [ 3 ] [ 4 ] Today, thanks to space probes, very high-resolution images of surface features on Mars and Mercury are available, and the classical nomenclature based on albedo features has fallen somewhat into disuse, although it is still used ...
Albedo Anthropomorphics, or Albedo for short, is a furry comic book anthology series which was credited with starting the furry comic book subgenre that featured sophisticated stories with talking animals primarily intended for an adult audience. [1] The first issue of Albedo was published in 1983; [2] the most recent issue was published in ...
Cloud albedo is a measure of the albedo or reflectivity of a cloud. Clouds regulate the amount of solar radiation absorbed by a planet and its solar surface irradiance . Generally, increased cloud cover correlates to a higher albedo and a lower absorption of solar energy .
An albedometer is an instrument used to measure the albedo (reflecting radiation) of a surface. An albedometer is mostly used to measure the reflectance of earths surface. It is also useful to evaluate thermal effects in buildings and generation capacity with bifacial solar photovoltaic panels. Often it consists of two pyranometers: one facing ...
