Explain heat budget of the Earth.
✓
Answer
Every square foot on the surface of the earth every day.
About $700$ calories of solar energy is available over an area of km.
It is the total solar energy received in the upper layers of the atmosphere.
Much of it is destroyed before it reaches the earth's surface.
About $15\%$ of the sun's energy is reflected back into space by clouds. And about $25\%$ of solar energy is absorbed by water vapor and water particles.
$33\%$ of the sun's energy is reflected back into space by clouds and about $25\%$ of the sun's energy is dispersed.
Of which $9\%$ returns to Earth in the form of heat dissipated in space and $16\%$ in all four directions.
