No, not all of the radiation from the sun is absorbed by Earth. Approximately 30% of incoming solar radiation is reflected back into space by clouds, other bright surfaces, and the atmosphere itself. The remaining 70% of the solar energy is absorbed by the Earth's atmosphere and surface.

Of the 70% of solar energy that is absorbed by the Earth system, about 23% is absorbed by the atmosphere and 48% is absorbed by the surface. Therefore, about 71% of the total incoming solar energy is absorbed by the Earth system.

The atmosphere absorbs solar energy in a variety of ways. Water vapor, ozone, and other atmospheric gases absorb solar radiation at specific wavelengths. Dust and other airborne particles also absorb solar energy.

The solar energy that is absorbed by the atmosphere is used to power atmospheric processes, such as evaporation, convection, and precipitation. The solar energy that is absorbed by the surface is used to heat the land and oceans, which in turn drives the global climate system.

So, to answer your question, about 23% of the solar energy that reaches Earth's atmosphere is absorbed by the atmosphere.

In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface. The Earth receives 174,000 terawatts (TW) of incoming solar radiation at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. It's not possible to give exact numbers, but nearly 30% of the Sun's incoming energy is reflected by the atmosphere and the surface. Another 23% is absorbed by the atmosphere. Hence only about 47% reaches Earth's surface and is absorbed by it. 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. The heat absorbed by the atmosphere is eventually radiated back into space (PW). Of all of the solar energy reaching the Earth, about 30% is reflected back into space from the atmosphere, clouds, and surface of the Earth. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth. The intensity of radiation emitted by the sun has its maximum value at a wavelength 510 nm and that emitted by another star has the maximum value at 350 nm. If all human emissions of heat-trapping gases were to stop today, Earth's temperature would continue to rise for a few decades as ocean currents bring excess heat stored in the deep ocean back to the surface. Once this excess heat radiated out to space, Earth's temperature would stabilize. 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. About 50% of solar energy that strikes the top of the atmosphere reaches Earth's surface. About 30% is reflected back to space. The remaining 20% of the energy is absorbed by clouds and atmospheric gases. Of all of the solar energy reaching the Earth, about 30% is reflected back into space from the atmosphere, clouds, and surface of the Earth. Another 23% of the energy is absorbed by the water vapor, clouds, and dust in the atmosphere, where it is converted into heat. Around 30% of the incoming radiation is reflected back to space and does not heat the surface, leaving the other 70% to be absorbed by the atmosphere and the Earth's surface. Because it is colder than the Sun, the Earth radiates energy at wavelengths that are far longer.

The contribution of the solar radiation at the top of the atmosphere is measured as TSI (Total Solar Irradiance) and it is approximated as 1360 watts per metre square at 1AU distance.
