It is radiated by many of the gases in the lower atmosphere.
Troposphere does not absorb solar radiation. All other layers do not absorb.

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%
Asteroids are the rocky planet remnants orbiting the solar system in the asteroid belt. Collisions between these objects may leave debris that can enter the Earth's atmosphere and become meteorites.
Approximately 47% of solar radiation that reaches the Earth's atmosphere makes it to the surface. The rest is either absorbed or scattered by the atmosphere and clouds. This direct solar radiation is crucial for photosynthesis and influences climate and weather patterns.

The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
Solar radiation—The sun emits energy in the form of electromagnetic radiation, which heats the Earth's atmosphere. Infrared radiation—The Earth's surface absorbs solar radiation and emits heat energy in the form of infrared radiation, which warms the atmosphere. Convection—The warmed air near the Earth's surface rises, carrying heat energy higher into the atmosphere and contributing to the overall warming.
The energy exchange between space, the atmosphere, and Earth's surface produces a balance of incoming solar radiation and outgoing thermal radiation. Solar energy is absorbed by the Earth's surface, which then emits thermal radiation back into the atmosphere. Greenhouse gases in the atmosphere trap some of this thermal radiation, leading to the warming of the Earth's surface.
The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
The atmosphere is heated chiefly by radiation from Earth's surface because the Earth's surface absorbs solar energy and emits it as infrared radiation. This infrared radiation is then trapped by greenhouse gases in the atmosphere, causing the atmosphere to be heated. Direct solar radiation contributes to heating the Earth's surface, which in turn warms the atmosphere through convection and radiation.
Troposphere does not absorb solar radiation. All other layers do not absorb.
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
UV
The increase in carbon dioxide in the atmosphere means that more solar radiation (in the form of infra-red heat from the warmed earth) is absorbed in the atmosphere and prevented from escaping to space. It will not change the transmission of incoming solar radiation through the atmosphere.
The trapping of energy from the sun by Earth's atmosphere is called the greenhouse effect. Solar radiation passes through the atmosphere to heat the Earth's surface, which then emits infrared radiation. Some of this infrared radiation is trapped by greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, creating a warming effect that helps maintain Earth's temperature.
The solar radiation can be divided into many parts. The UV radiation part of it helps to form the ozone.
