Incoming solar energy intercepted by the earth
7.3: Atmospheric Radiation and Earth''s Climate
The solar irradiance is essentially parallel by the time it gets to Earth, so it is intercepted by Earth''s cross-section, which is just pi r Earth squared. At Earth''s surface, there is the incoming solar radiation energy that is absorbed and the tropospheric downward emitted infrared radiation, equivalent to three times the incoming solar
Chapter 2 The global energy balance
Earth intercepting the solar energy flux is πa2 where ais the radius of the Earth (Fig. 2.5), Solar power incident on the Earth = S0πa2 =1.74 ×1017 W using the data in Table 1.1. Not all o f this radiation is absorbed by the Earth; a significant fraction is reflected. The ratio of reflected to incident solar energy is called the albedo, α.
2.2: Insolation
The Earth is "constantly" bathed in solar radiation. On average, the Earth receives 1368 W/m 2 of solar radiation at the outer edge of the atmosphere, called the "solar constant". However, the actual amount received at the edge of the atmosphere and at the Earth''s surface varies from place to place and day to day on account of the orientation
Solar influence on the Earth System | Sun Climate
Clouds and Solar Radiation. Solar radiation is the primary energy source for Earth. On a global, long-term scale, the incoming solar radiation is approximately balanced by the reflected (the difference between incident and absorbed) solar radiation and the emitted terrestrial radiation or outgoing longwave radiation (ORL).

Insolation stands for incoming solar radiation.-the flow of solar energy intercepted by an exposed surface for the case of a uniformly spherical earth with no atmosphere. Daily insolation, which is the average insolation rate over a 24-hour day, depends on two factors: (1) the angle at which the sun''s rays strike the earth, and (2) the

BASICS IN SOLAR RADIATION AT EARTH SURFACE
The sun produces a vast amount of energy. The energy emitted by the sun is called solar energy or solar radiation. Despite the considerable distance between the sun and the earth, the amount of solar energy reaching the earth is substantial. At any one time, the earth intercepts approximately 180 106 GW. Solar radiation is the

Read the statements and choose the correct option.
As the earth is a geoid resembling a sphere, the sun''s rays fall obliquely at the top of the atmosphere and the earth intercepts a very small portion of the sun''s energy. In other words, Insolation is the incoming solar energy intercepted by the earth. The amount of insolation decreases from the equator towards the poles.
Climate and Earth''s Energy Budget
On average, 340 watts per square meter of solar energy arrives at the top of the atmosphere. Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). Most solar energy is absorbed at the surface, while most heat is radiated back to space by the atmosphere.
6 FAQs about [Incoming solar energy intercepted by the earth]
Why is solar radiation absorbed only by earth's surface?
Therefore, radiation is absorbed only by Earth's surface. And the atmosphere's emissivity is zero. That solar radiation energy, which is just the difference between the incoming solar radiation energy and the reflected solar radiation energy, equals Earth's infrared radiation energy outgoing to space.
How does solar energy work?
Solar energy acts as a that can be harnessed. Almost all of the Earth 's energy input comes from the sun. Not all of the sunlight that strikes the top of the atmosphere is converted into energy at the surface of the Earth. The Solar energy to the Earth refers to this energy that hits the surface of the Earth itself.
How does infrared energy balance incoming solar radiation?
At the top of the atmosphere, the difference of the incoming solar radiation energy minus the amount of solar radiation energy that is scattered back to space (this difference being the amount of solar radiation energy absorbed by the Earth system) must balance the emitted infrared radiation energy for radiative equilibrium to hold.
How much solar radiation does the Earth intercept?
Figure 2 The Earth intercepts an amount of solar radiation equivalent to that falling on a disc with the same radius (R ) as the Earth, facing the Sun: this comes to (1368 × π R 2 ) W, where π R 2 is the area of the disc (in m 2).
What percentage of solar energy is absorbed by Earth?
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.
How does solar energy affect Earth's climate system?
This energy plays no role in Earth’s climate system. About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.
