Albedo (/ ælˈbiːdoʊ / 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).

Albedo, fraction of light that is reflected by a body or surface. It is commonly used in astronomy to describe the reflective properties of planets, satellites, and asteroids. It is an important consideration in climatology since recent decreases in the albedo in the Arctic has increased heat absorption at the surface.

What is Albedo? Albedo is the fraction of light that a surface reflects. If it is all reflected, the albedo is equal to 1. If 30% is reflected, the albedo is 0.3. The albedo of Earth's surface (atmosphere, ocean, land surfaces) determines how much incoming solar energy, or light, is immediately reflected back to space.

2024年9月24日 · Albedo is a critical concept in Earth science and astronomy, influencing climate dynamics, planetary temperatures, and the study of celestial bodies. Understanding albedo helps scientists model Earth’s energy budget, track the effects of climate change, and study the properties of planets in our solar system.

Albedo is a measurement, expressed as a fraction, of the amount of radiation scattered from a surface or an object. In this chapter we describe those albedos most commonly used and describe methods to calculate them in cases where analytical solutions are difficult, if not impossible, to obtain.

2024年11月11日 · Albedo is the measure of how much light something reflects. The more light something absorbs, the lower its albedo and the warmer it will get. Areas with high albedo reflect more light and energy and stay cooler.

Albedo is ratio of the light received by a body to the light reflected by that body. Albedo values range from 0 (pitch black) to 1 (perfect reflector). Technical Definition. Geometric albedo is the ratio of a body’s brightness at zero phase angle to the brightness of a perfectly diffusing disk with the same position and apparent size as the body.

Albedo is the amount of sunlight (solar radiation) reflected by a surface, and is usually expressed as a percentage or a decimal value, with 1 being a perfect reflector and 0 absorbing all incoming light.

Albedo is a calculation of diffuse solar radiation reflected from the total solar radiation, and it's determined on a range of zero to 1, with 0 corresponding to a black body that absorbs every incident radiation and 1 corresponding to a body that reflects almost every incident radiation.

Albedo refers to the fraction of sunlight that a surface reflects, with the rest being absorbed. It plays a crucial role in remote sensing of surface and atmospheric properties, influencing surface temperature, vegetation cover, and atmospheric composition.
