The long-wave radiation absorbed by greenhouse gases is primarily in the form of infrared radiation. After the Earth's surface absorbs solar energy, it re-emits this energy as infrared radiation, which has longer wavelengths compared to the short-wave radiation from the sun. Greenhouse gases in the atmosphere, such as carbon dioxide and methane, absorb and re-radiate this infrared radiation, contributing to the greenhouse effect and warming the planet.
Infrared radiation is the type of radiation that gets trapped on Earth's surface by the greenhouse effect. This radiation is emitted by the Earth's surface in response to the incoming solar radiation and is absorbed and re-emitted by greenhouse gases in the atmosphere, leading to the warming of the planet.
Greenhouse gases (water, carbon dioxide and methane, mostly) allow light to enter the earth's atmosphere. It comes in as solar radiation and about half of it is absorbed by the earth's surface. This radiation is converted to heat energy, which in turn, radiates infrared (longwave) radiation back out into space. Much of this infrared radiation is captured by the greenhouse gases in the troposphere (the lowest layer of the atmosphere). The warmed greenhouse gases then heat the air around them, and re-radiate the heat back down to earth, contributing to the greenhouse effect.

Greenhouse gases primarily trap infrared radiation emitted by the Earth's surface. When sunlight reaches the Earth, it is absorbed and re-emitted as infrared radiation. Greenhouse gases, such as carbon dioxide and methane, absorb some of this infrared radiation and re-radiate it in all directions, including back towards the Earth's surface, contributing to the greenhouse effect and warming the atmosphere.
The Earth's surface radiates thermal infrared radiation to cool down. This energy is absorbed from the sun during the day and then emitted as heat at night to balance the energy received.
Longwave radiation refers to infrared radiation emitted by the Earth's surface and atmosphere, which can be absorbed by greenhouse gases and contribute to warming the atmosphere. Shortwave radiation, such as sunlight, is absorbed by the Earth's surface and then re-emitted as longwave radiation. This difference in wavelengths affects how energy is distributed in the atmosphere, with longwave radiation playing a key role in the greenhouse effect and shortwave radiation driving the Earth's climate system.
Greenhouse gases absorb shortwave radiation by allowing it to pass through the Earth's atmosphere and reach the surface. Once the radiation hits the surface, it is absorbed and re-emitted as longwave radiation. Greenhouse gases then trap this longwave radiation, preventing it from escaping back into space and causing the Earth's temperature to rise.
Earth's radiation is primarily longwave. Shortwave radiation from the sun enters the Earth's atmosphere, where some is absorbed and re-radiated as longwave radiation. This longwave radiation is what is emitted back out into space.

Shortwave radiation comes from the sun and is absorbed by the Earth's surface, warming it. Longwave radiation is emitted by the Earth's surface and is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet. These differences in radiation play a crucial role in regulating the Earth's temperature and climate.
The trapping of longwave radiation in the atmosphere is known as the greenhouse effect. This process involves certain gases, such as carbon dioxide and water vapor, absorbing and re-emitting infrared radiation, which helps to warm the Earth's surface.
Carbon dioxide (CO2) is the most powerful absorber of longwave radiation emitted by Earth, leading to the greenhouse effect and global warming.
Infrared radiation, also known as longwave radiation, heats the Earth's surface by being absorbed and re-radiated back from the surface. This process helps to maintain Earth's temperature within a habitable range for life.
The primary source of radiation for both Earth's atmosphere and the greenhouse effect is the sun. Solar radiation warms the Earth's surface, which then emits infrared radiation. Some of this infrared radiation is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet.
Infrared radiation is the type of radiation that gets trapped on Earth's surface by the greenhouse effect. This radiation is emitted by the Earth's surface in response to the incoming solar radiation and is absorbed and re-emitted by greenhouse gases in the atmosphere, leading to the warming of the planet.
No greenhouse gas absorbs the sun's incoming shortwave radiation. All the greenhouse gases (carbon dioxide, methane, water vapor, nitrous oxide, CFCs etc) absorb the outgoing longwave infrared radiation from the warmed surface of the earth.
The process of longwave radiation trapping through the greenhouse effect has the greatest role in warming the upper troposphere. Greenhouse gases, such as carbon dioxide and water vapor, trap outgoing longwave radiation, leading to a warming effect in the upper troposphere. This process is critical for maintaining Earth's temperature and climate.
