A greenhouse gas is a gas in an atmosphere that absorbs and emits radiant energy within the thermal infrared range.

It is conventionally the symbol for «emissivity» — loosely, «the ability to emit radiant energy.»
Not exact matches
Another disadvantage is the high levels of radiant heat energy produced by high - pressure sodium lamps; up to 75 % of the energy from HPS lamps that is not converted to light is emitted as radiant heat energy, causing the surface of the lamps to reach temperatures as high as 450 °C.
In some active galactic nuclei, you have a black hole and accretion disk and the majority of the power is associated with these outflowing jets, far more than is associated with the radiant energy that is emitted by the accretion disk and the hot gas surrounding it.
They then looked at another source of data: that of the Clouds» and Earth's Radiant Energy System (CERES) satellite instruments which measure fluxes of reflected and emitted radiation from Earth to space, to help scientists understand how the climate varies over time.
The intensity and distribution of radiant energy within this range is governed by the temperature of the emitting surface.
PS when molecular collisions are frequent relative to photon emissions and absorptions (as is generally the case in most of the mass of the atmosphere), the radiant heat absorbed by any population of molecules is transfered to the heat of the whole population within some volume, and molecules that emit photons can then gain energy from other molecules.
On average the radiant energy in joules absorbed equals the radiant energy in joules later «re» - emitted.
No surface can emit energy any faster than energy can be transferred to the radiant surface.
The Earth and all of its subsystems are gray - bodies because they do not absorb the whole load of radiant energy that they receive from the Sun and they do not emit the whole load of radiant energy that they absorb.»
Radiant solar (shortwave) energy is transformed into sensible heat (related to temperature), latent energy (involving different water states), potential energy (involving gravity and altitude) and kinetic energy (involving motion) before being emitted as longwave infrared radiant Radiant solar (shortwave) energy is transformed into sensible heat (related to temperature), latent energy (involving different water states), potential energy (involving gravity and altitude) and kinetic energy (involving motion) before being emitted as longwave infrared radiant radiant energy.
temperature is a function of energy but certainly not = energy Temperature is a measure of the average internal kinetic energy of matter and also a [non-linear] measure of the radiant energy emitted by a body.
Black objects emit more radiant energy (cools faster) than a white or silver to its cooler surroundings.
This means that 63.3 % (248Wm - 2) of the 391Wm - 2 emitted as LWIR radiant energy from the surface is absorbed by water vapour in 120m of traverse and the remainder 140Wm - 2 leaves the atmosphere as it is transparent to it.
And it represents Radiant energy in a small frequency (wave number) increment emitted from a small element of surface area (/ m ^ 2) into a small elemental solid angle (/ sr) to some particular direction in space.
This means that 63.3 % (248Wm - 2) of the 391Wm - 2 emitted as LWIR radiant energy from the surface is absorbed by water vapour in 120m of traverse.
The fundamental equation of radiative transfer at the emitting surface of an astronomical body, relating changes in radiant - energy flux to changes in temperature, is the Stefan - Boltzmann equation --
whereF is radiant - energy flux at the emitting surface; εis emissivity, set at 1 for a blackbody that absorbs and emits all irradiance reaching its emitting surface (by Kirchhoff's law of radiative transfer, absorption and emission are equal and simultaneous), 0 for a whitebody that reflects all irradiance, and (0, 1) for a graybody that partly absorbs / emits and partly reflects; and σ ≈ 5.67 x 10 — 8 is the Stefan - Boltzmann constant.
Radiant solar (shortwave) energy is transformed into sensible heat, latent energy (involving different water states), potential energy, and kinetic energy before being emitted as longwave infrared energy.
