Climate and Earth''s Energy Budget

The Sun''s surface temperature is 5,500° C, and its peak radiation is in visible wavelengths of light. Earth''s effective temperature—the temperature it appears when viewed from space—is -20° C, and it radiates energy that peaks in thermal infrared wavelengths.

Earth''s energy flow

Flows on the Earths Surface. Although the solar energy flow is the most dominant flow, it is not the only source of energy on the Earth. The remaining 120 000 TW, or approximately 70% of the initial energy, that reaches the surface of the Earth comes down and warms the atmosphere. This portion of the pathway can be seen in Figure 2.

Solar Radiation

The amount of solar energy reaching the Earth is 70 percent. The surface of the Earth absorbs 51 percent of the insolation. Water vapor and dust account for 16 percent of the energy absorbed. The other 3 percent is absorbed by clouds. Of the 30 percent that is reflected back into space, 6 percent is reflected by air and dust.

Approximately What Percentage of Solar Energy Is Lost Before

Solar energy is dispersed and lost before it even reaches the Earth''s surface, mainly due to factors like reflection back into space.Approximately 30% of solar energy is reflected back, preventing it from being absorbed by the Earth. This loss through reflection is a significant component of the Earth''s energy budget and plays a vital role in climate regulation.

6 FAQs about [What percentage of solar energy reaches earth s surface]

How much solar energy is absorbed by the Earth?

Due to reflection by the atmosphere, clouds, and Earth's surface we can approximate that 70% of solar energy incident on the edge of the Earth's atmosphere is actually absorbed by the Earth. Taking this into account, the actual average amount of solar energy absorbed by the Earth amounts to:

How much solar energy does Earth have?

At Earth’s average distance from the Sun (about 150 million kilometers), the average intensity of solar energy reaching the top of the atmosphere directly facing the Sun is about 1,360 watts per square meter, according to measurements made by the most recent NASA satellite missions. This amount of power is known as the total solar irradiance.

How much energy does Earth receive?

In its orbit around the Sun, the part of Earth that faces the Sun receives approximately 1,371 W/m2 of energy. Averaged over the area of Earth's full sphere, the energy from sunlight coming to the top of the atmosphere is approximately 340 W/m2. [Detailed view of Earth's energy budget]

How does solar energy reach Earth?

The majority of energy from the Sun reaches Earth in the form of visible and infrared radiation. Just over half of this incoming solar energy ultimately reaches the ground. The rest is reflected away by low-level, thick, white clouds or ice or gets absorbed by the atmosphere. The solar energy that makes it to the ground warms Earth’s surface.

How do you determine the average amount of solar energy reaches Earth?

To determine the average amount of solar energy that reaches the Earth, we must consider what the Earth "looks like" to the Sun. When looking at Earth from the Sun, only one half of the Earth can be seen.

How much energy does the sun emit?

Over the course of one solar cycle (one 11-year period), the Sun’s emitted energy varies on average at about 0.1 percent. That may not sound like a lot, but the Sun emits a large amount of energy – 1,361 watts per square meter. Even fluctuations at just a tenth of a percent can affect Earth.
