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

absorb by gases

Opposite

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
