Global Radiation Budget Variations
What do you think the global distribution of the Earth’s
longwave r adiation exiting the top of the atmosphere should look like?
What latitude should have the maximum emitted radiation?
What latitude should have the least?
What determines the amount of emitted radiation from any object?

Note:
• General decrease as move toward thepoles
• Minimumjust north of the Equator
• Maximumnorth and south of Equatorial minimum
