radiant energy
101Greenhouse Gases — Those gases, such as water vapor, carbon dioxide, nitrous oxide, methane, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride, that are transparent to solar (short wave) radiation but opaque to long wave (infrared)… …
102Emissivity — The ratio of the radiant energy (heat) leaving (being emitted by) a surface to that of a black body at the same temperature and with the same area; expressed as a number between 0 and 1. *** The property of emitting radiation; possessed by… …
