This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
The percentage of radiation reflected by an object is called that objects albedo. High albedo is very reflective, low albedo means most of the light that strikes the object will be absorbed.
You might be looking for the surface's albedo.
The percentage of solar radiation reflected from a surface is called the albedo.
Albedo.
"albedo" for apex!
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
Thermal IR radiation.
The Solar System object with the highest albedo is Europa with a reflectivity of 0.64. Earth by comparison is 0.367. Europe is smooth and covered in fresh (clean) ice. So smooth and white would reflect the most.
the amount of solar radiation/the surface area of atmosphere/8
The quantity of solar radiation incident normally per minute on 1 cm2 surface of a perfectly black body on the Earth.
About 6% of incoming solar radiation is reflected back into space from the atmosphere and 4% by the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
About 50% of the incoming solar radiation reaches the surface of the planet. The rest is reflected or absorbed by the atmosphere & clouds, and a small portion is reflected by the oceans and land.
Solar radiation that is not reflected is absorbed by clouds, the atmosphere and the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%Source: (NASA)

A perfectly black surface has an albedo of 0 (all radiation is absorbed).A perfectly mirror-finished surface has an albedo of 1.0 (all radiation is reflected).Earth's average albedo is about 0.3. In other words, about 30 percent of incoming solar radiation is reflected back into space (from land, sea, clouds, ice and atmosphere) and 70 percent is absorbed.From point to point on the Earth's surface, the albedo varies; high for clouds or snow, low for cities and paved areas, intermediate for vegetation. Overall, averaging the bright areas with the cities, the Earth's albedo is about 0.3 or perhaps just a little higher; 0.34 or so.Well, all of it is not. Some of it is absorbed by the oceans, some by dry land, and some by the ice caps.
It increases the amount of solar radiation that is reflected into space
Some is absorbed by molecules in the atmosphere (such as ultraviolet absorption by ozone), some is absorbed on the surface, and some is reflected by clouds or the surface back into space. The surface will re-radiate much of the absorbed solar radiation as infrared (thermal) radiation, and some of this is then absorbed by atmospheric gases such as carbon dioxide and methane.
The wavelength is longer. Energy is re-radiated by the Earth as infrared radiation (heat).
