Emissivity Coefficients for some common Materials

Radiation emissivities of some 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 materials:

MaterialEmissivity Coefficient
- ε -
Water 0.993 - 0.998
Ice 0.98
Snow 0.969 - 0.997
Sand 0.949 - 0.962
Granite 0.898
Green Grass 0.975 - 0.986
