Sentences with phrase «total radiation it emits»

To determine the location of a star's habitable zone, one must first learn how much total radiation it emits.

Under steady - state conditions, the total radiation absorbed by the Earth must match the total radiation emitted by the Earth; that's what radiative balance or imbalance means in the climate literature.

Not exact matches

Although only 1 percent of the sun's energy is emitted at ultraviolet wavelengths between 200 and 300 nanometers, the decrease in this radiation from 1 July 1981 to 30 June 1985 accounted for 19 percent of the decrease in the total irradiance over the same period.»

Eventually the surface reaches a point where it emits enough IR that the half making it out into space balance the total amount of incoming SW and LW radiation.

Each higher and cooler layer in turn emits thermal radiation corresponding to its temperature; and much of that also escapes directly to space around the absorption bands of the higher atmosphere layers; and so on; so that the total LWIR emission from the earth should then be a composite of roughly BB spectra but with source temepratures ranging ove the entire surface Temeprature range, as well as the range of atmospheric emitting Temperatures.

Thus, long - term variations of TSI (with account for their direct and secondary, based on feedback effects, influence) are the main fundamental cause of climate changes since variations of the Earth climate is mainly determined by a long - term imbalance between the energy of solar radiation entering the upper layers of the Earth's atmosphere and the total energy emitted from the Earth back to space.»

Prof Claes Johnson (see Computational Blackbody Radiation) and I are in total agreement as to the reason being that blackbodies do not convert the energy in radiation that was emitted spontaneously by a cooler source than their own temperature.

You can not measure total incident or emitted radiation with any instrument known to man.

The first shell will recieve 235w / m2 and heat to some temperature where it will emit a total of radiation that will keep it in equilibrium with the surroundings.

The shell will still have to emit the total radiation of the planet to space, but the planet will not be warmed as much by the radiation of the shell.

It is assumed that all the solar radiation from relevant absorption band makes it to the CO2 boxes through all the other boxes and does this constantly with no loss and if it did the model might be correct, as it is there are tens of thousands of other boxes between each CO2 box so the absorption and the storing and the re emitting of this narrow band can not be total or anywhere near total and the incoming source is not constant nor does all all the solar radiation actually make it the CO2 boxes, it would only be a proportion the rest being intercepted and dissipated beforehand.

The total radiation leaving one side of the layer is the external radiation reflected back by the interface, radiation emitted internally by the layer and transmitted through the interface, radiation scattered by sites inside the layer and transmitted through the interface, and radiation transmitted through the layer from the surroundings on the opposite side.

Total internal reflection of scattered and internally emitted radiation affects the radiation leaving the layer and the temperature profile.

-- Yes, it may be correct in so far as they can say that; «around 10 % of the wavebands emitted by IR radiation are made up of wave - lengths that can not be absorbed by «Greenhouse Gases» (GHGs), but that can not possibly mean that 0.04 %, in the case of CO2 concentration but certainly less than 10 % of the Atmosphere as a total has got what must be a «supernatural» ability to stop LWR.

This is because some of the gases absorb and emit radiation at the same frequencies as others, so that the total greenhouse effect is not simply the sum of the influence of each gas.

The right side is total absorbed solar radiation — upward emitted atmospheric radiation.

If that «aperure» surface, happens to be a real planar aperture in the thermally impenetrable wall of the cavity, then radiation will be emitted from that aperture in the same cosice (Lambertian) pattern, and the total emitted energy, will simply be pi times the axial intensity (normal to the aperture).

First, the quote is not dealing with what the result of reabsorbing its own radiation is but how to calculate the total emitted power of a body with a complex shape.

It clearly shows that the total emitted radiation from the surface is 38.9 MJ while the total solar absorbed over the same period is 24.0 MJ.
