WebSolar radiation is the energy emitted by the Sun, which is sent in all directions through space as electromagnetic waves. Emitted by the surface of the Sun, this energy influences atmospheric and climatological processes. It is also, directly and indirectly, responsible for common phenomena, such as plant photosynthesis, keeping the planet at a ... WebA 100% albedo (highest albedo possible) would be all the solar radiation being reflected away. A 0% albedo would mean none of the solar radiation is reflection and thus all is absorbed into or transmitted through the substance. First we will examine sun angle.

WebAbout 29 percent of the solar energy that arrives at the top of the atmosphere is reflected back to space by clouds, atmospheric particles, or bright ground surfaces like sea ice and snow. This energy plays no role in Earth’s climate system. WebOverall, Earth reflects about 29% of the incoming solar radiation, and therefore, we say the Earth’s average albedo is 0.29. Snow and ice, airborne particles, and certain gases have high albedos and reflect different amounts of sunlight back into space. WebThe temperature of the atmosphere and surface is influenced by electromagnetic radiation, and this radiation is traditionally divided into two types: insolation from the Sun and emittance from the surface and the atmosphere.

"WebFrom 3, let's multiply that by the solid angle subtended by the moon as viewed from the Earth as this will give us the amount of the reflected energy that hits the Earth. So, 100 W/m 2 × 6.5 × 10 − 5 = 6.5 mW/m 2. Assume the moon is at roughly the same distance from the Sun as the Earth and so receives the same amount of solar energy / area.
