| emissivity |
also called emittance - the non-dimensional ratio of the radiance emitted from an object at a particular wavelength to the radiance that a blackbody would emit at that same temperature and wavelength. Thus a surface with an emissivity equal to 1.0 is a blackbody. All natural surfaces have emissivities less than 1.0, although most earth land surfaces have infrared emissivities between 0.9 and 1.0.

| Emil |
A member of a group of Sierra Gordan terrorists known as the Menshevikistas. The group threatened to blow up the Cobra Consulate in New York if Cobra did not withdraw its support of Sierra Gordo's current government. Emil and the other surviving terrorists failed and were arrested. Their current status is unknown. (SM #7)

| emissivity |
The relative ability of a surface to reflect or emit heat by radiation. Emissivity factors range from 0.00 to 1.00 and are typically measured in a U-Factor ( or its inverse R-Factor). The lower the emissivity, the less heat that is emitted through a windows system.
