When the energy from an external source enters Earth's atmosphere, it interacts with the atmosphere and gets
Refracted-> Scattered -> Absorbed .
The radiant energy from the Sun, after passing through the atmosphere reaches the Earth's surface, and three things happen
i) some portion of the energy is reflected by the
earth surface,
ii) some portion of energy is transmitted into the surface
iii) and some portion of it is absorbed and emitted by the earth’s surface later on
Talking specifically about the reflectance property of the earth's surface which affects the reflected rays
- The reflection intensity depends on the surface roughness, absorption coefficient, and the angles of incidence and reflection.
- Surface roughness is a function of the wavelength of incident radiation
- Depending upon whether the surface is smooth or rough, the reflection can be either specular or diffuse.
