To understand albedo, you must understand energy balance. Earth’s climate is driven by the sun’s energy. Of the total solar irradiance (approximately 1,361 watts per square meter at the top of the atmosphere), roughly 30% is immediately reflected back to space by clouds, atmospheric particles, and reflective surfaces. The remaining 70% is absorbed, warming the planet.
. A value of 0 represents a "black body" that absorbs all incoming radiation, while a value of 1 represents a perfect mirror that reflects everything. High Albedo: Surfaces like fresh snow Albedo
Albedo can be measured using various techniques: To understand albedo, you must understand energy balance
is a simple yet powerful measure of reflectivity . Derived from the Latin word for "whiteness," it describes the fraction of sunlight reflected by a surface back into space. While it might sound like a niche technical term, it is actually a cornerstone of climate science, planetary physics, and even urban design. The Scale of Brightness Albedo is measured on a scale from The remaining 70% is absorbed, warming the planet
