Sentences with phrase «o2 absorb radiation»

Not exact matches

Okay, one little nit - picky issue with Q2 is that O2 and N2 actually DO absorb infrared radiation, just at shorter wavelengths than matter for the Earth's infrared emission spectrum (3 - 27 microns, with a peak around 9 microns or so).

This is very difficult to explain to a non-scientist, but basically it is an established scientific fact based on long - established experiment and theory that simple molecules like O2 and N2 don't absorb infra - red radiation whereas more complicate molecules such as CO2 and H2O can.

Okay, one little nit - picky issue with Q2 is that O2 and N2 actually DO absorb infrared radiation, just at shorter wavelengths than matter for the Earth's infrared emission spectrum (3 - 27 microns, with a peak around 9 microns or so).

It is more complicated than that, but since the judge only wants to know why O2 and N2 do not absorb IR radiation I thought what I wrote originally was sufficient.

ie does a slightly lower density of air mean a slightly lower ground level temperature (temperature normally decreases with height at the lower air density), so that in reality adding CO2 and subtracting more O2 actually causes miniscule or trivial global COOLING, and the (unused) ability of the changed atmosphere to absorb radiation energy and transmit it to the rest of the air is overruled or limited by the ideal gas law?

Diatomic molecules like O2 and N2 are transparent to that radiation and will never fit the definition of a greenhouse gas, no matter that they absorb heat via other means.

I explained to you on your own website that, whether you call them greenhouse gases or not, CO2, CH4, N20 behave differently from N2 and O2: GHGs absorb outgoing long wave radiation and N2 and O2 don't.

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

If you are designing an atmospheric model with molecules that absorb or emit ir energy, N2 and O2 would not be modeled as absorbing or emitting ir energy through vibrational interactions with electromagnetic radiation.

It is, effectively, at the blackbody radiation temperature (and all molecules including N2 and O2 absorb and emit blackbody radiation — this seems to not be understood by many).

Molecules like N2 and O2 (99 % of Earth's atmosphere) can't absorb longwave radiation because identical diatomic molecules don't bend (they are symmetric).

Finally, I will note the absurdity of DeanMJackson calling scientists liars because in simplified explanations they call N2 (which absorbs 0.045 % of upward IR radiation) and O2 (which absorbs 0.029 %) transparent to IR radiation.

The VUV (< 200 nm) absorption due to the O2 Schuman Runge bands essentially wipe out all of the radiation that would be absorbed by methane / CO2 and water vapor as discussed in the here and here.

Water vapor is massively more effective than N2 or O2 in absorbing radiation in the troposphere.

But if the N2 and O2 molecules are radiating like a dense body without absorbing any radiation, as so many seem to be claiming, wouldn't one expect to see a BB radiation between ~ 8μ and ~ 14μ (1250 cm ^ -1 and 715 cm ^ -1 wave number).
