Global heat budget and Latitude and energy balance

• The global heat budget is the balance of incoming and outgoing solar radiation.
• Insolation is the incoming solar energy (Heat)
• Albedo is the measure of how much sunlight a surface reflects.
• Reflected heat in the form of long wave radiation gets trapped in our atmosphere and keep or planet warm. Giving a natural green house effect.
• 23% of short wave solar energy is absorbed by atmosphere (4% clouds and 19% water vapour gases and dust)
• 25% of short wave solar energy is reflected by atmosphere (17% clouds and 8% atmospheric gases)
• 52% solar energy reaches the Earth's Surface.
• 46% of solar energy is absorbed by Earth's surface (land and water)
• 6% of solar energy is reflected by Earth's surface.
• Albedo is 31% and Absorbsion is 69%
