Energy balance of Earth
The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.

- Transmission
- Both short and long wave radiation
As light encounters gas molecules and particulates in the atmosphere, the pathway that the light follows changes

3. The Earth-Atmosphere Energy Balance
The earth-atmosphere energy balance is the balance between incoming energy from the
Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as
shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to
space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's
surface.
4. Insolation-Atmosphere Interaction
Refers to what happens after the intercepted solar radiation enters the atmosphere
● - Transmission
● - Both short and long wave radiation
As light encounters gas molecules and particulates in the atmosphere, the pathway that the
light follows changes
● Diffusion (scattering)
● Refraction
● Reflection
● Absorption
5. Diffusion
● The Sun's rays are essentially parallel as they reach the Earth's
surface.
● As they encounter various particles in the atmosphere, some light
rays are bounced in all the different directions.
a. " Diffusion, or scattering
b. " Some light scattered back into space (7%)
c. " Some light scattered to the Earth's surface (20%)
● Diffusion increases as sun angle decreases
