Sentences with phrase «effective radiating surface»

The increased effective radiating surface area of atmospheric CO2 would also act like a stepping stone for heat to leave the planet but how much cooling these effects have is anyones guess.

Not exact matches

Like Sirius, however, Altair radiates much more in ultraviolet wavelengths than Sol, and, not surprisingly, the European Space Agency has used ultraviolet spectral flux distribution data to determine stellar effective temperatures and surface gravities, including those of Altair.

Like Sirius, however, Vega radiates much more in ultraviolet wavelengths than Sol, and, not surprisingly, the European Space Agency has used ultraviolet spectral flux distribution data to determine stellar effective temperatures and surface gravities, including those of Vega.

But, it does not eliminate it... because the increase in the effective radiating level still occurs... and the temperature at the surface is determined by extrapolating down from this level using the lapse rate.

If the effective TOA is slightly cooler then the effective surface needs to radiate at a higher temperature.

That implies that if the effective temperature is 288 K, watts radiated per square meter of surface will not be 390.7 but 0.95 * 390.7 = 371.165 watts

The Earth's surface will be warmer — because we have increased the distance from the surface to the effective radiating altitude.

Involving the adiabatic lapse rate is an effort to reconcile radiative physics with the Ideal Gas Law but taking the effective radiating height as the appropriate «surface» does not work for reasons that I will discuss in more detail in Parts B and C of this article.

Additionally the effective radiating height is not a suitable «surface» for the purposes of the S - B Law.

i) The S - B Law requires that a raised effective radiating height results in a higher surface temperature.

Therefore according to the Ideal Gas Law additional GHGs will simply raise the effective radiating height, reduce the density at the surface and result in a net zero change in surface temperature.

Applying the adiabatic lapse rate from the effective radiating height to the surface as per the S - B Law then gives a surface temperature which is some 33C higher than it «should» be.

3) Failure to realize that the sign of the thermal response to a raised effective radiating height is reversed under the Gas Laws so as to negate any effect on surface temperature.

Nevertheless the effective radiating height is used as a starting point for back calculating the expected surface temperature from the S - B Law.

It seems to me that the only significant role that the greenhouse gases perform is to perhaps insulate the Earth Surface and to radiate to space at their effective radiating level.

For the 120th time (okay, maybe it's only the 19th), the temperature at the earth's surface is determined by the lapse rate and the level in the atmosphere at which the temperature is constrained, which is the effective radiating level, i.e., the average level from which radiation can successfully escape to space.

This actually turns out to be a negative feedback... i.e., the lapse rate is reduced slightly so the temperature at the surface does not have to rise quite as much as would be predicted by just considering the change in the effective radiating level and a fixed lapse rate.)
