Sentences with phrase «now absorbing radiation»

But, because the water vapor and CO2 spectra overlap, the total increase is actually only about 7 % since the water vapor is now absorbing radiation previously absorbed by CO2.

Not exact matches

Ultraviolet light from early, blueish stars (illustrated) interacted with hydrogen gas, causing it to absorb background radiation, and creating a signature scientists have now detected.

In addition, they must have been able to resist the biologically destructive ultraviolet radiation in sunlight, which was not absorbed by a layer of ozone as it is now.

We now put an air parcel between the observer and the back wall, a parcel which absorbs IR radiation exiting from the wall to the observer.

It is true that this lost solar heating now adds to the LW flux coming from below, but the skin layer only absorbs a tiny fraction of that, so the increase in absorped LW flux from below is less than the decrease in the absorbed SW radiation.

The fact that CO2 absorbs and re-emits long - wave radiation has been pretty well established for well over a century now.

Now the radiation pressure in the cavity between surface and absorber has increased by a factor of 2.7, due to the higher temperature, but the additional expansion and cooling this causes is still utterly negligible (a further 1.7 parts in 1E11).

Now with absorptivity (the proportion of incident radiation absorbed) set at 0.8, while the emissivity varies.

If CO2 and H2O molecules now are cooled below the previous equilibrium point by having their radiation allowed to escape to outer space, then I believe these molecules must then tend to absorb more energy than yield energy with each interaction with the other components of the atmosphere until that atmosphere as a whole reaches a new thermal equilibrium where the net radiation going out and the net radiation coming in (primarily from the sun and the surrounding atmosphere) is the same.

Then that lowest atmosphere layer emit and a 50 - 50 split sends it half up and half down; and the up ward is again absorbed by a higher and now cooler layer; which in turn emits but now at a lower temperature; until finally some much higher and much cooler layer gets to emit radiation that actually escapes to space and that radiating temperature is the one that must balance with the incoming TSI insolation rate.

Now Chilingar and his colleagues bring out the simple equation balancing the effective radiation temperature of the earth with the solar radiation absorbed.

However, a darker Earth now absorbs more sunlight, tipping the scales to net warming from shortwave radiation.»

That greenhouse gases being absent does not effect the one third of solar radiation being absorbed by clouds Or the surface albedo can jump from 12 % to 30 % Or the greenhouse gases being absent but still have clouds to reflect radiation Or the IR (not now absorbed) by the clouds will not obey Kirchoff's Law on reaching the planet surface And so on.

Now there is this theory according to which addition of carbon dioxide to the atmosphere will cause the air to get warm because carbon dioxide absorbs outgoing infrared radiation and converts it to heat.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

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.

That changes the colour of the water very noticeably meaning that radiation at certain wavelengths which previously would have passed straight through is now absorbed.

In other words, * we can observe the increase of CO2 in atmosphere above the ocean, * CO2 absorbs some part of the outgoing radiation from the surface of the ocean which increases somewhat the temperature of the air * The increasing of temperature causes the (slight) increase of the (already existing) back radiation * This (now increased) back radiation is absorbed by the surface skin layer of the ocean which means that the energy delivered by the back radiation to the surface skin layer is now slightly higher * This additional energy will now be distributed over the channels that are participating in the heat transfer from the absorbing surface skin layer to both the air above the skin layer and the bulk of the ocean.

CO2 intercepts and absorbs this energy and now CO2 warms up respectively and therefore begins to increase it's radiation, — half of which (estimates may vary) returns to the surface and is now near to the end of it's first circuit.

This is important with regard to H20, as humidity drops rapidly and the wave lengths that are absorbed by this molecule now escape at a greatly increased rate and so back radiation diminishes accordingly.

That happens partly through «new» absorption of radiation that more or less used to escape directly from the surface, as well as absorption and re-emission of radiation that used to get absorbed and re-emitted at lower layers, but now (at higher CO2) does so at higher layers.

In this case, what happens is the whole surface - atmospheric column is now receiving more (absorbed) solar radiation than it is emitting terrestrial radiation to space.
