Sentences with phrase «longwave radiation emitted»

This NASA site (not GISS: ^) http://earthobservatory.nasa.gov/Features/Clouds/, is about clouds and says, in part: «When a cloud absorbs longwave radiation emitted by the Earth's surface, the cloud reemits a portion of the energy to outer space and a portion back toward the surface.»

However, clouds also trap longwave radiation emitted by the Earth, as does water vapor.

About 70 % of the longwave radiation emitted from the Earth's surface is absorbed by the atmosphere's greenhouse gases.

A satellite map of the outgoing longwave radiation emitted by Earth in September 2008 demonstrates not only geographical variations but also those caused by cloud presence.

Not exact matches

Radiation emitted from Earth is called longwave radiation; it falls within the infrared portion of the spectrum and has typical wavelengths of 4 to 30 micrometres (0.0002 to 0.001 inch).

Absorption of thermal radiation cools the thermal spectra of the earth as seen from space, radiation emitted by de-excitation is what results in the further warming of the surface, and the surface continues to warm until the rate at which energy is radiated from the earth's climate system (given the increased opacity of the atmosphere to longwave radiation) is equal to the rate at which energy enters it.

The outgoing longwave radiation is composed not just of the radiation that leaks through to the top from the warm lower layers, but also of the «cold» radiation emitted from the upper atmosphere.

The imbalance is not between IR absorbed and IR emitted by a layer of atmosphere, but between the incoming shortwave solar energy from space and the outgoing longwave energy emitted to space, due to the increasing difference between the ground temperature and the temperature of the level from which re-emitted radiation can escape to space.

In the case of an increase in greenhouse gases (which cause a warming), that implies that the planet will be absorbing more solar radiation than it emits as longwave radiation.

In the absence of solar heating, there is an equilibrium «skin temperature» that would be approached in the uppermost atmosphere (above the effective emitting altitude) which is only dependent on the outgoing longwave (LW) radiation to space in the case where optical properties in the LW part of the spectrum are invariant over wavelength (this skin temperature will be colder than the temperature at the effective emitting altitude).

O2 and N2 do not indeed, emit or absorb radiation in the longwave thermal region.

where is the vertically integrated energy flux in the atmosphere, is the net radiative energy input to an atmospheric column (the difference between absorbed shortwave radiation and emitted longwave radiation), and is the oceanic energy uptake at the surface.

The net atmospheric energy input near the equator is the small residual (~ 20 W m2) of large cancellations between absorbed shortwave radiation (~ 320 W m2), emitted longwave radiation (~ 250 W m2), and oceanic energy uptake (~ 50 W m2).

«Tropical variations in emitted outgoing longwave (LW) radiation are found to closely track changes in the El Nino - Southern Oscillation (ENSO).

Emitted LONGWAVE Radiation Heat resulting from the absorption of incoming shortwave radiation is emitted as longwave radEmitted LONGWAVE Radiation Heat resulting from the absorption of incoming shortwave radiation is emitted as longwave raLONGWAVE Radiation Heat resulting from the absorption of incoming shortwave radiation is emitted as longwave rademitted as longwave ralongwave radiation.

In turn, the warmed atmosphere emits longwave radiation, some of which radiates toward the Earth's surface, keeping our planet warm and generally comfortable.

Most of the emitted longwave radiation warms the lower atmosphere, which in turn warms our planet's surface.»

GREENHOUSE EFFECT Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower atmosphere.

For the longwave, most objects are very good at absorbing and emitting infrared radiation.

As the atmosphere warms, it will emit more radiation over the whole longwave spectrum.

As per my posts above, it is possible for DLR to increase more than evaporation, and so the warming from the DLR beats the cooling from evaporation, leading to a warming whereby the system is moving towards equilibrium by increasing temperature and hence increasing sensible heat flux and emitted longwave radiation.

Greenhouse gases allow much of the Sun's shortwave radiation to pass through them but absorb or trap the longwave, infrared radiation emitted by the Earth's surface.

Yet, the longwave radiation that happens to be emitted downward from the added GHG does have to pass through more dense GHGs so some of it will be absorbed and re-emitted upwards.

After the initial absorption by the CO2 of the longwave radiation from the earth, most of the re-emitted longwave radiation should be emitted upward into space.»

«Clouds also block some of the longwave radiation that would be emitted back to space, so that a decrease in global cloud amount would increase the amount of solar radiation reaching the Earth's surface (more heating), but also increase the amount radiated back to space (more cooling).»

An increase in the atmosphere's concentration of carbon dioxide is also a climate forcing: it leads to a situation in which the planet absorbs more solar radiation than it emits to space as longwave radiation.

Persistent small climate changes are difficult to detect within the diurnal, regional, and seasonal variance of Earth's reflected (shortwave) and emitted (longwave) energy — hence a continuous long - term (decades) record of Earth's radiation budget (ERB) is needed to identify subtle long - term shifts related to climate change.4 With the demanifesting of TSIS and ERBS from NPOESS, ERB measurements will end with the last CERES on Aqua (or perhaps NPP, pending addition of CERES FM - 5 onto NPP), the TIM record will end with Glory, and the SIM record with SORCE.

The latter is made up of two large terms: the emitted radiation from the surface and the downwelling longwave radiation coming back from the atmosphere.

That means that newly emitted longwave radiation from the Earth's surface will spend more time in the lower reaches of the Atmosphere and therefore contribute to heating the N2 and O2 and other components of the air more than before.

(1) The warmed Earth emits longwave radiation towards the Atmosphere.»

Any mass, including a mass of gas, that has a temperature above absolute zero, will emit longwave radiation in random directions and at a variety of wavelengths, peaking at the wavelength corrresponding to the temperature of that gas, as indicated in the first graphic.
