Record Label : surface_longwave_emissivity
Record Title : Surface Longwave Emissivity
CF Standard Name : surface_longwave_emissivity
Record Description : Emissivity is the ratio of the power emitted by an object to the power that would be emitted by a perfect black body having the same temperature as the object. The emissivity is assumed to be an integral over all wavelengths, unless a coordinate of radiation_wavelength or radiation_frequency is included to specify either the wavelength or frequency. The surface called "surface" means the lower boundary of the atmosphere. "longwave" means longwave radiation.
