WebFor a given material, this luminance is weighted by a coefficient between 0 and 1 and called emissivity. We write it ε. This coefficient can depend on the wavelength, the incidence and the temperature: ε(λ,T,θ,φ). ... The enclosure E is a thermally insulated cryostat generally filled with liquid nitrogen. Helium is used when it is desired ... WebDec 5, 2024 · Combined with our global energy balance calculation, this implies that the average bolometric emissivity of Pluto's nitrogen ice is probably in the range 0.47 - 0.72. This is consistent with the low emissivities estimated for Triton based on Voyager, and may have implications for Pluto's atmospheric seasonal variations, as discussed below.

Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface (a black body).
