Radiation - Surfaces Emissivity Coefficients

Radiation emissivity of common materials like water, ice, snow, grass and more.

The emissivity coefficient - ε - indicates the radiation of heat from a body according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal black body where the emissivity coefficient ε = 1.

Emissivity coefficients - ε - for some common material surfaces:

Radiation - Surfaces Emissivity Coefficients
MaterialEmissivity Coefficient
- ε -
Water (0 - 100oC) 0.95 - 0.963
Ice 0.96 - 0.99
Snow 0.96 - 0.98
Sand 0.9
Granite 0.96
Green Grass 0.975 - 0.986
