WebThe amount of energy reflected by a surface is called albedo. Dark colors have an albedo close to zero, meaning little or no energy is reflected. Pale colors have an albedo close to 100%, meaning nearly all the energy is reflected. WebEtymology. The term regolith combines two Greek words: rhegos (ῥῆγος), 'blanket', and lithos (), 'rock'. The American geologist George P. Merrill first defined the term in 1897, writing: .

WebSoil Albedo (SOL_ALB(top layer)) Soil albedo is the ratio of the amount of solar radiation reflected by a body to the amount incident upon it, expressed as a fraction. It can be calculated from a linear regression between albedo and the Chroma Meter Munsell color value⁽³⁾. The FAO data contains a Munsell color value for each MUID in the Soil 1 WebAlbedo 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, …

Albedo is the measure of the diffuse reflection of solar radiation out of the total solar radiation and 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.
