Sentences with phrase «reflect radiation emitted»

Clouds also absorb and reflect radiation emitted from Earth's surface.
10 How the Atmosphere Affects Climate (Page 273) Earth's atmosphere can absorb and reflect radiation emitted from the Sun and from Earth's surface.

Not exact matches

The dosimeter can determine the level of free radicals by comparing the amount of microwave radiation emitted with the amount that is reflected.
They then looked at another source of data: that of the Clouds» and Earth's Radiant Energy System (CERES) satellite instruments which measure fluxes of reflected and emitted radiation from Earth to space, to help scientists understand how the climate varies over time.
Dark matter is an unseen substance that does not, as CERN explains, absorb, reflect or emit electromagnetic radiation such as light.
Direct imaging can be done by using starlight reflected off the planet or thermal infrared radiation emitted by the planet.
What other things in the Earth system will change when it warms up that will affect how much SW radiation is reflected back into space [eg ice - albedo feedback, cloud changes] or affect what proportion of emitted LW radiation is allowed to escape to space [eg Water Vapour, cloud changes].
But in the transparent windows, the radiation field is «hotter» (being a combination of reflected SWR and emitted «hot» ground LWR), so in the lines, it is «colder»: the lines appear thus as absorption lines from the space, with a lower brightness temperature than the continuum.
Gases and clouds in the atmosphere absorb, emit, and reflect radiation.
Because the climate system derives virtually all its energy from the Sun, zero balance implies that, globally, the amount of incoming solar radiation on average must be equal to the sum of the outgoing reflected solar radiation and the outgoing thermal infrared radiation emitted by the climate system.
However, since the Earth reflects about 30 % of the incoming sunlight, the planet's effective temperature (the temperature of a blackbody that would emit the same amount of radiation) is about − 18 °C, about 33 °C below the actual surface temperature of about 14 °C.
If CO2 actually possessed the capacity to emit «powerful back radiation» its thermal conductivity results would reflect this by being larger not smaller.
The total radiation leaving one side of the layer is the external radiation reflected back by the interface, radiation emitted internally by the layer and transmitted through the interface, radiation scattered by sites inside the layer and transmitted through the interface, and radiation transmitted through the layer from the surroundings on the opposite side.
Forests also emit large amounts of water vapour, which reflects solar radiation back into space.
CO; 2 Observations of the Infrared Radiative Properties of the Ocean «[I] t is necessary to understand the physical variables contributing to sea surface emitted and reflected radiation to space.The emissivity of the ocean surface varies with view angle and sea state, the reflection of sky radiation also depends on view angle and sea state, and the absorption of atmospheric constituents such as water vapor, aerosols, and subdivisible clouds affect transmittance.»
Postma described a black body warmed by a heat source and claimed that you can not make it warmer by reflecting that emitted radiation back.
If the surface is ALREADY emitting radiation that is «hotter», i.e. more energetic then the «back radiation» will in effect just be reflected again.
Most of the radiation measured as coming from the ocean surface is actually either been reflected or is being emitted by molecules evaporated from the ocean surface.
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.
I would like to play around with energy balance numbers from OLR, reflected solar, surface emitted radiation and see whether global tau presents itself as a useful number in practice.
Your survival blanket reflecting 90 % is not an issue, the notion an emitting body will absorb 90 % of it's own reflected radiation is ridiculous.
Both have 90 % of the emitted radiation reflected back and then absorbed.
