Sentences with phrase «non radiative gases»

It is my understanding that radiative gases provide an additional radiative route for energy loss to space that non radiative gases fail to provide.

There have been many «heated» discussions on various blogs as to the hypothetical structure of the atmosphere composed of no greenhouse gases, only non radiative gases.

N2 and O2 are generally called non radiative gases in climate science, but they do absorb and emit IR.

Not exact matches

3) Under the assumption of radiative equilibrium, it can be shown that the surface temperature of a planet would slightly and non linearily increase with the concentration of IR active gases (primarily H2O) if and only if radiation was the only mean for energy transfer.

Without the radiative forcing supplied by CO2 and the other non condensing greenhouse gases, the terrestrial greenhouse would collapse, plunging the global climate into an icebound Earth state.»

A non radiative atmosphere should not be considered a «bizarre case» but rather the base line for all modelling of levels of radiative gases in the atmosphere.

«in an isotropic non GHG world, the net would be zero, as the mean conduction flux would equalize, but in our earth it is still nearly zero» if the atmosphere were isothermal at the same temperature as the surface then exactly the downwelling radiation absorbed by the surface would be equal to the radiation of th surface absorbed by the air (or rather by its trace gases) and both numbers would be (1 - 2E3 (t (nu)-RRB--RRB- pi B (nu, T) where t (nu) is the optical thickness, B the Planck function, nu the optical frequency and T the temperature; as the flow from the air absorbed by the surface is equal to the flow from the surface absorbed by the air, the radiative heat transfer is zero between surface and air.

You had to elaborate your answer by saying that gases with non polar molecule symmetry do not absorb or emit energy within the temperature parameters with any application in engineering, e.g. O2, N2, H2..., while gases with polar molecule symmetries are significant absorbers and emitters of radiative energy, e.g. H2O, CO2, SO3... for engineering applications, depending of their density, temperature and pressure in a given environment.
