What is Energy & Budget.
What are………1. Radiation
2. Reflection
3. Absorption
What type of radiation.
How much radiation coming from the sun.
What type of mediums there in atmosphere.
Totally how much absorption & Reflection.
Is Earth……
Gaining Energy
In Balance
Losing Energy

Energy is the ability to change the
surroundings.
Budget is the amount of incoming or outgoing
energy allocated to a system
Energy&Budget

Radiation is Rays which coming from the
surface.
Visible wavelength

something
Radiation
absorb by gases

40W/m² is directly to the atmosphere to the outer space. Other due to scattering. Total 239W/m².
Greenhouse gases and
also clouds. Absorbed
long wave radiations
and then reflect back
towards earth.

Is Earth……Gaining Energy In Balance Losing Energy?
Add up two outflow of energy then
1 Reflection 2 Long wave radiation
Reflection=101.
9Longwave Radiation=
238.5
Total Reflection=
340.4
