- 1E (spectral emissive power)W/(m^2*um)
Rate at which radiation of wavelength lambda is emitted in all directions from a surface, per unit wavelength interval d(lambda) about lambda and per unit surface area - 2Diffuse EmitterE(lambda) = pi*I(lamda)
An emitter whose radiation has the same intensity in all directions. - 3Spectral IrradiationG, units W/(m^2*um)
Rate at which radiation from all directions of wavelength lambda is incident on a surface, per unit area of the surface and per unit wavelength interval d(lambda) about lambda. - 4RadiosityJ = E + pG
Rate at which all radiation leaves a surface per unit area.
This includes emitted radiation from the surface, and reflected radiation (a fraction of incident irradiation).
