The ratio of reflected to incident light; albedo can be expressed as either a percentage or a fraction of 1. Snow covered areas have a high albedo (up to about 0.9 or 90%) due to their white color, while vegetation has a low albedo (generally about 0.1 or 10%) due to the dark color and light absorbed for photosynthesis. Clouds have an intermediate albedo and are the most important contributor to the Earth's albedo. The Earth's aggregate albedo is approximately 0.3.

The proportion of incident radiation reflected by a surface. About 30% of the incoming solar energy is reflected back to space from the earth, of which 25% is reflected by clouds and 5% by the surface or by atmospheric molecules or suspended particles. The clouds and atmospheric gases and particles absorb 25% of the incident radiation with the remainder absorbed at the surface. See Peixoto and Oort (1992), Ch. 6.
Fraction of light reflected by a surface, such as ice, or by an entire planet. Studying a planet's albedo can help determine the composition of its surface.
The fraction of solar radiation that is reflected by a surface (such as the earth).

The albedo is a measure of the reflective quality of a surface. Albedo is the ratio of the amount of light striking a surface to the amount reflected from the surface and is typically given as a percent. A surface having an albedo of 50% would reflect half of the light reaching it, whereas an albedo of 0% would indicate that no sunlight is reflected. Dry sand reflects approximately 35% of the sunlight that strikes its surface. Fresh snow reflects approximately 85%.

Albedo - the amount (usually quoted as a percentage %) of incident light that is reflected from a surface. Different surfaces have different reflectances - snow has a very high reflectance (around 80%) and so appears white, whilst the sea can absorb almost all light falling onto it and thus appears dark with a very low (3%) reflectance.

Reflectivity of an object; ratio of reflected light to incident light.
The ratio of light reflected from a solar system object to that received by it. A complete reflection gives a albedo of 1.0 or 100 percent).
Refers to the ratio of light from the sun that is reflected by the Earth's surface to the light received by it. Unreflected light is converted to infrared radiation (i.e., heat), which causes atmospheric warming (see "radiative forcing"). Thus, surfaces with a high albedo (e.g., snow and ice) generally contribute to cooling, whereas surfaces with a low albedo (e.g., forests) generally contribute to warming. Changes in land use that significantly alter the characteristics of land surfaces can therefore influence the climate through changes in albedo.

The fraction of sunlight that is reflected by earth, ice, and clouds back into space. The value for today's earth is about one- third (i.e., two-thirds of the sunlight is absorbed).
is the percentage of the incoming radiation that is reflected off a surface. An albedo of one indicates that 100 percent of the radiation is reflected. Fresh snow has a high albedo (0.7 to 0.9), indicating that 70 to 90 percent of the radiation received is reflected; glacier ice has a lower albedo of 0.2 to 0.4. Braided Stream Where more sediment is being brought to any part of a stream than it can remove, the building of bars becomes excessive, and the stream develops an intricate network of interlacing channels, the stream is said to be braided. Often more is deposited than can be removed by specific fluvial processes.

Albedo is the ratio of solar radiation falling on the surface of the earth compared to the amount reflected from it.
Albedo is the ratio of reflected to incident electromagnetic radiation power. It is a unitless measure indicative of a surface's or body's reflectivity. The word is derived from albus, a Latin word for "white".
