Sentences with phrase «where atmospheric radiation»

Not exact matches

Low energy electrons are ubiquitous and are known to play important role in variety of phenomena relevant to astrochemistry (where they participate in synthesis of new molecules), in radiation biology (where they cause chemical changes in living cell, plasma chemistry), atmospheric chemistry, radioactive waste management and nanolithography — to name but a few.
As for «explanations», Hank, (138) I am trying to locate one of Gavin's where I think he said that «in this context», presumably atmospheric radiation, «heat and energy are equivalent».
The whole issue is that any level above what is often called the «effective radiating level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling radiation... except not quite, because convection distributes heating higher than this level, the stratosphere marks the point where convection gives out and there is high static stability.
Refering to bands where optical thickness is constant over the interval of each band, if the atmospheric LW absorption is limited to some band (that doesn't cover all LW radiation), than increases in OLR in response to surface warming will occur outside that band, so OLR will drop within the band — there will still be some portion of stratospheric or near - TOA cooling that will be transient, but some will remain at full equilibrium.
This is not the case with surface - to - air heat exchange (which involves evapo - transpiration, sensible heat flows, and radiation) or even within the troposphere where impacts of latent heating on atmospheric circulations are realized on scales ranging from hundreds of meters to thousands of kilometers.
The basic ingredients are easy to list: — absorption / emission properties (or spectroscopic parameters) of CO2 at atmospheric pressures, i.e. data presently available from HITRAN - database combined with models of line broadening — observed properties of the atmosphere where most important features include clouds and moisture content, but many other factors have some influence — computer model of the transmission of radiation along the lines of MODTRAN or GENLN2
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.
where latent heat release and net radiation into the atmospheric column, R, balance heat divergence, and the relatively weak contribution from sensible heat transport from the land surface to the atmospheric column has been neglected.
Since atmospheric WV is expected to increase as a result of higher temperatures, the «WV - enhanced» greenhouse effect should cause some of the solar radiation that would otherwise reach the Earth's surface (in the absence of the enhanced GH effect) to be absorbed in the atmosphere, where that energy can perhaps be more easily lost to space (the complexity of the climate system permitting).
So it is the ordinary atmosphere that is radiating the atmospheric LWIR radiation; except at very high prehaps ionoospheric levels where the mean free path is such that the GHG species can spontaneously decay to the ground state, before a collision occurs.
... where the effects of atmospheric gases is shown on both incomeing and outgoing radiation.
I plan to make additional postings in this series, addressing some implications of the 9μ to 12μ portion of the longwave radiation band where the Atmosphere is nearly - transparent, as well as other atmospheric «greenhouse» issues.
Since it takes several hundred years for the deep ocean water to cycle up to the top, where it can be warmed up and lose CO2, it makes sense to suppose that if a warming event is initiated by something else (like changes in the amount and spatial distribution of incoming solar radiation,) the concomitant rise in atmospheric CO2 (which would enhance the initial warming) might lag behind by several hundred years.
If not the downwelling atmospheric radiation where is all the extra energy necessary to balance coming from?
Looking up into the sky, it is clear that SOMETHING is emitting close to a BB radiation curve @ ~ 265 K (the atmospheric temperature near the surface), but only above ~ 14 um or below ~ 8 um (which happens to be where H2o & CO2 emit well).
It is the first time I've seen an explanation where the energy represented by the specific frequencies absorbed by GHG molecules are transferred to non-GHGs through collision (and then reemitted by the non-GHGs in the atmospheric windows — almost everyone believes the non-GHGs absorb and emit no IR radiation at all — some bad textbooks mis - educated everyone somewhere along the line).
