Sentences with phrase «ir radiation from the earth»

Greenhouse gases «trap» radiative energy because they absorbed IR radiation from the Earth's surface which then continually «bounces up and down».

Since there is about 50 % variable cloud cover at any given time and clouds can reflect over 99 % of the IR radiation from the Earth's surface clouds are responsible for a likely 90 % of the Earth's greenhouse effect.

(2) Just saying the words «lapse rate» and «ideal gas equation» doesn't get you around having to explain how one could conserve energy if one considers the current surface temperature of the earth and imagines that one had an atmosphere transparent to IR radiation from the earth's surface.

Not exact matches

If it is correct, then the IR radiation emitted from the earth's surface and absorbed will be nearly completely thermalized and not re-emitted, i.e. it will heat the air.

Because the wavelength of emitted EM radiation varies with the temperature of the source, it does so in the form of longer - wave IR than that received from the Sun — the Earth's surface is significantly cooler than that of the Sun.

What the CO2 (both «cold, hot and warm CO2 ′) and other gasses do is to make the atmosphere more optically thick to thermal IR radiation emitted (mainly) from the Earth's surface [note2] which has consequences for the equilibrium temperature profile of the atmosphere.

eadler2 -[Upward IR radiation flux] is what stabilizes the earth's climate and prevents it from running away.

The Earth is much cooler than the Sun, this means that the energy re-emitted from the Earth's surface is lower in intensity than that emitted from the Sun, i.e. in the form of invisible infra - red (IR) radiation.

But it's when that volume is exposed to outside influences — like IR radiation from the solar - heated surface of the Earth passing through that volume — that a temperature change can occur as a result of adding more CO2 to the volume.

1) The influence of methane on the Earth energy balance is not due to the absorption peak at 3.3 µm because that wavelength has very little role in solar radiation and even less in IR radiated from the Earth.

In Earth's atmosphere, there is a «window» between the 8 and 12 micron band where there is virtually no absorption going on, and through which IR radiation passes out from the surface to space virtually unimpeded.

When the sun is no longer shining the surface of the earth will cool because upward radiation is continuing, and IR is taking energy from the earth into outer space.

However, the point is simply this: As long as you have an IR - absorbing atmosphere that is at a nonzero temperature, the earth's surface will have to be at a warmer temperature (in order to radiate away the energy that it receives from the sun) than it would be if the atmosphere did not absorb any of the IR radiation that the earth emits.

... you say that most of the energy leaving the system via IR emission (from CO2 in your example) is sourced from insolation, which would mean that only a small portion of the escaping CO2 radiation energy originates from earth's IR.

BPL (84) you say that most of the energy leaving the system via IR emission (from CO2 in your example) is sourced from insolation, which would mean that only a small portion of the escaping CO2 radiation energy originates from earth's IR.

You have to demonstrate that all radiation from the Earth surface IR radiation converted to 14 ~ 16um that CO2 can absorb more than its share of 0.039 % content.
