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
To store
something
Radiation

Albedo
Clouds & Atmosphere
79W/m².
78W/m².
79W/m² & 78W/m²
184W/m²
Earth’s Albedo
Earth’s total Albedo
Clouds 79W/m²+Earth23W/m²
102W/m²
239W/m² In
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
