Sentences with phrase «absorbing radiation mostly»

This skin of the skin layer would be absorbing radiation mostly emitted from layers above where the OLR is emitted.

These so - called starbursts are difficult to observe from Earth, as their dusty shrouds absorb much of the optical light from the stars and re-radiate it as longer - wavelength radiation to which Earth's atmosphere is mostly opaque.

So I agree with William, the cooling effect at the top of the atmosphere requires that the atmosphere be absorbing some incoming radiation (and that this absorption be (mostly) by non-greenhouse gasses).

Thus radiation emitted from below the TAU = 1 level gets mostly absorbed before it can get out to space.

Of the energy absorbed by the ocean, most is released locally to the atmosphere, mostly by evaporation and infrared radiation...

Increased human activity disproportionately in the northern hemisphere may lead to greater particulate (mostly soot like with relatively high absorptivity) deposition on Arctic ice which absorbs solar radiation and leads to the ice melting.

Incident solar radiation (mostly in the 2.7 micron band) is absorbed by carbon dioxide at various levels in the atmosphere.

AGW is a hypothesis that makes sense, namely: — GHGs absorb outgoing radiation, thereby contributing to warming (GH theory)-- CO2 is a GHG (as is water vapor plus some minor GHGs)-- CO2 concentrations have risen (mostly since measurements started in Mauna Loa in 1959)-- global temperature has risen since 1850 (in ~ 30 - year warming cycles with ~ 30 - year cycles of slight cooling in between)-- humans emit CO2 and other GHGs — ergo, human GHG emissions have very likely been a major contributor to higher GHG concentrations, very likely contributing to the observed warming

Then, especially when there is excessive cloud cover over the oceans, the Sun's energy absorbed above the clouds can actually make its way down to the ocean surface (and below) warming the oceans by non-radiative processes, not by direct solar radiation which mostly passes through the thin surface layer and could barely raise the mean temperature of an asphalt paved Earth above -35 C.

When you add GHGs to the atmosphere, it both emits more radiation towards space and earth and absorbs more radiation mostly from earth.

I mentioned that only to tell that even that tiny amount of solar radiation is mostly absorbed somewhere in the atmosphere.

Mindert, CO2 can not be an insulator because it readily emits the radiation it absorbs, and mostly away from the surface.

As obvious on figures 6 - A and 6 - B, Ttop and Ptop are determined by the water vapour that radiates over some 1900 cm - 1 much more than the 40 cm - 1 of the tropospheric CO2 near 614 cm - 1 and 718 cm - 1.; stratospheric radiation to the cosmos is not very important because the cooling of each layer is exactly equal to its heating mostly by UV absorbed by Ozone.

Now the water (H2O) in the form of a liquid or ice crystals, can and does scatter and reflect a good bit of the radiation that impinges on it, but in the case of the LWIR, I would expect it still to be mostly absorbed by the water rather than refected.

CO2 can only absorb terrestrial EMR that has wave length 14 - 16 microns out of the significant range (mostly within 5 - 50 microns) of terrestrial radiation.

This is possible only because most of this radiation is absorbed in the atmosphere, and what actually escapes out into space is mostly emitted from colder atmosphere.

This is because the radiation is completely absorbed at some frequencies, while CO2 remains mostly transparent at others.

But let's put these unconventional views aside for a moment, and accept that certain atmospheric gases (e.g., CO2, for one) DO absorb more heat radiation than their more neutral cohorts (e.g., nitrogen and oxygen mostly).

These same absorbers of heat radiation (e.g., CO2) also EMIT the absorbed heat very fast to the surrounding air (mostly nitrogen and oxygen again).

* The ground is a little warmer than the atmosphere, so that factor will mean some more photons going up than down (but since the back radiation is mostly from low layers, the atmosphere emitting the back radiation will not be that much cooler than the land so the effect from temperature will not be TOO great) * The ground is close to a black body for IR (emissivity = 1 for all IR frequencies), but the atmosphere has bands where it does not emit or absorb well (emissivity ~ 0) and other bands where it does emit or absorb well (emissivity ~ 1).
