  2. Albedo - Wikipedia

    en.wikipedia.org/wiki/Albedo

    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).

  3. Cloud albedo - Wikipedia

    en.wikipedia.org/wiki/Cloud_albedo

    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 .

  4. Albedo feature - Wikipedia

    en.wikipedia.org/wiki/Albedo_feature

    In planetary geology, an albedo feature is a large area on the surface of a planet (or other Solar System body) which shows a contrast in brightness or darkness with adjacent areas. Historically, albedo features were the first (and usually only) features to be seen and named on Mars and Mercury .

  5. Geometric albedo - Wikipedia

    en.wikipedia.org/wiki/Geometric_albedo

    Diffuse reflection on sphere and flat disk, each for the case of a geometric albedo of 1. For the hypothetical case of a plane surface, the geometric albedo is the albedo of the surface when the illumination is provided by a beam of radiation that comes in perpendicular to the surface.

  6. Ice–albedo feedback - Wikipedia

    en.wikipedia.org/wiki/Ice–albedo_feedback

    Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far more solar energy back to space than open water or any other land cover . [ 1 ]

  7. Bond albedo - Wikipedia

    en.wikipedia.org/wiki/Bond_albedo

    The Bond albedo is a value strictly between 0 and 1, as it includes all possible scattered light (but not radiation from the body itself). This is in contrast to other definitions of albedo such as the geometric albedo, which can be above 1. In general, though, the Bond albedo may be greater or smaller than the geometric albedo, depending on ...

  9. List of albedo features on Mercury - Wikipedia

    en.wikipedia.org/wiki/List_of_albedo_features_on...

    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.
