Sentences with phrase «surface emissivity»
Surface emissivity refers to the ability of a material or surface to emit or release thermal radiation. It shows how well or poorly a surface can give off heat through radiation. A high surface emissivity means that the material releases heat easily, while a low surface emissivity means that it retains heat. Full definition
The real GHE must be reduction of surface emissivity by GHGs turning off that emission.
