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:
- ε -
|Water||0.993 - 0.998|
|Snow||0.969 - 0.997|
|Sand||0.949 - 0.962|
|Green Grass||0.975 - 0.986|
