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).
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 ...
Source explains: "Earth’s albedo (reflectivity, in percent), seasonality removed. (Note:) We take the first 10 years of data as the base period (defining the zero point for anomalies) as the longest that avoids intrusion into the time of IMO restrictions on ship emissions.
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 albedo effect causing a fraction of light to be reflected by the planet; The greenhouse effect for planets with an atmosphere; Energy generated internally by a planet itself due to radioactive decay, tidal heating, and adiabatic contraction due to cooling. The analysis only considers the Sun's heat for a planet in a Solar System.
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).
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 ...
