Enceladus, a moon of Saturn, has one of the highest known optical albedos of any body in the Solar System, with an albedo of 0.99. Another notable high-albedo body is Eris, with an albedo of 0.96. [65] Many small objects in the outer Solar System [66] and asteroid belt have low albedos down to about 0.05. [67]
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
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 .
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 ...
Lunar Reconnaissance Orbiter Wide Angle Camera image of Reiner Gamma Another view of Reiner Gamma swirls Mare Ingenii Swirls east of Firsov crater, from Apollo 10. Lunar swirls are enigmatic features found across the Moon's surface, which are characterized by having a high albedo, appearing optically immature (i.e. having the optical characteristics of a relatively young regolith), and (often ...
The Kuiper quadrangle, located in a heavily cratered region of Mercury, includes the young, 55-km-diameter crater Kuiper (11° S., 31.5° ), which has the highest albedo recorded on the planet, [1] and the small crater Hun Kal (0.6° S., 20.0° ), which is the principal reference point for Mercurian longitude (Davies and Batson, 1975).
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 ]
Clouds have a higher albedo than the underlying ocean, which causes more incoming solar radiation to be reflected back to space. Since the tops of tropical systems are much cooler than the surface of the Earth, the presence of high convective clouds cools the climate system. The most recognizable cloud system in the tropics is the hurricane. In ...
