Sentences with phrase «infrared radiation escaping»

The visible solar radiation mostly heats the surface, not the atmosphere, whereas most of the infrared radiation escaping to space is emitted from the upper atmosphere, not the surface.

The evidence here comes from satellite measurements of infrared radiation escaping from the earth into outer space, from measurements of sunlight reflected from clouds and from measurements of the temperature the earth's surface or of the troposphere, the roughly 10 km thick layer of the atmosphere above the earth's surface that is filled with churning air and clouds, heated from below at the earth's surface, and cooled at the top by radiation into space.

In bands where greenhouse gases (or clouds) absorb a lot, there is less, not more, infrared radiation escaping into space.

The visible solar radiation mostly heats the surface, not the atmosphere, whereas most of the infrared radiation escaping to space is emitted from the upper atmosphere, not the surface.

Because the lapse rate is not zero, changing the altitude near the top of the atmosphere where infrared radiation escapes freely to space allows adjustment of the surface temperature by means of the addition of greenhouse gases.

Not exact matches

«For comparison, the amount of carbon dioxide in the atmosphere in 2005 was about 380,000 ppbv — so carbon dioxide absorption of escaping infrared radiation is much more important,» Rowland adds.

Using their computer models as a guide, the researchers found a variant of polyethylene commonly used in battery making that has a specific nanostructure that is opaque to visible light yet is transparent to infrared radiation, which could let body heat escape.

It's not totally about how much infrared from the surface that is blocked (currently about 90 % of surface emissions is absorbed by greenhouse gases), its also about the height within the atmosphere from which radiation escapes.

More greenhouse gases in the atmosphere impede the escape of thermal infrared radiation to space, and thereby raise temperature.

Much of this radiation escapes as infrared.

More greenhouse gases in the atmosphere impede the escape of thermal infrared radiation to space, and thereby raise temperature.

1) Greenhouse gasses absorb infrared radiation in the atmosphere and re-emit much of it back toward the surface, thus warming the planet (less heat escapes; Fourier, 1824).

That's entirely due to the clouds blocking and re-radiating the infrared radiation that would otherwise escape to space.

Thus, for a well - coupled convecting troposphere, one defines the climate sensitivity (in the absence of feedback) as 1 / [d (SB) / dT] = 1 / (4 * sigma * T ^ 3), where T in this case is actually the emission temperature of the planet where infrared radiation leaks out to space (analogous to the photosphere of the sun, where eventually the outer layers of the sun become optically thin to visible radiation, and allow that energy to escape to space), not the surface temperature.

CO2 traps heat According to radiative physics and decades of laboratory measurements, increased CO2 in the atmosphere is expected / predicted to absorb more infrared radiation as it escapes back out to space.

The heat caused by infrared radiation is absorbed by greenhouse gases such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere.

Some of the heat escapes from the surface as out - going long wavelenght infrared radiation (OLR).

Less often, the CO2 will re-emit infrared radiation in a random direction, either to be absorbed again, or to escape from Earth's atmosphere altogether.

At this point, very simple physics takes over, and you are pretty much doomed, by what scientists refer to as the «radiative» properties of carbon dioxide molecules (which trap infrared heat radiation that would otherwise escape to space), to have a warming planet.

Or, put another way, methane is more effectual than carbon dioxide at absorbing infrared radiation emitted from the earth's surface and preventing it from escaping into space.

Carbon dioxide absorbs infrared radiation in the middle of its 15 mm band to the extent that radiation in the middle of this band can not escape unimpeded: this absorption is saturated.

Molecules of greenhouse gases, especially water vapor and carbon dioxide, «recycle» some of the heat energy which would otherwise escape from Earth in the form of infrared radiation.

This matters because clouds are fundamental regulators of how much solar radiation makes it to the Earth's surface (rather than being reflected back to space by white cloud tops), and how much infrared or «longwave» radiation escapes back to space once again.

These gases absorb infrared radiation emitted by Earth and release that energy into the atmosphere rather than allowing it to escape to space.

If the GHGs weren't there, the infrared radiation would escape to space and we'd be living (or dead, rather) on a very cold planet.

Increasing the concentration of these gases in the atmosphere increases the thickness of this insulator, therefore increasing the atmosphere's ability to block the escape of infrared radiation.

4 Greenhouse Effect Certain atmospheric gases trap some of the infrared radiation that escapes from the Earth, making the Earth warmer than it would be otherwise.

The greenhouse gases are building up, making it harder for the infrared heat radiation of the earth to escape into space.

For instance, it is still a common popularized formulation that greenhouse gases «trap» infrared radiation in the atmosphere or at least «slow its escape.»

... Infrared radiation is carried slowly aloft by air currents, and its eventual escape into space is delayed by greenhouse gases» (emphasis added).
