IES Exam 1 Lecture 4

Earth's Energy Budget and Temperature Pt. 1

TermDefinition
Shortwave Energy Origin Sun Atmosphere downwards
Longwave Energy Origin Emitted by Earth and Earth temperature objects Goes off in upward direction
Longwave Absorption Atmosphere is good at absorbing it and radiating it back down to the surface
Heat Budget Energy moving around w/in Earth System
emission Converts Heat energy to EMR
Absorption Converts EMR to heat energy
Transmission Movement of EMR through object w/out changing the subject
Water Albedo Angle dependent 10-60%
Snow and Ice Albedo 80-95%
High Angle Water Albedo High absorption, low albedo
Low Angle Water Albedo High reflectivity, high albedo
Direct Radiation Straight path of radiation from Sun to surface
Diffuse Radiation Light is scattered through atmosphere as it comes down
Rayleigh Scattering Short wavelengths scatter more easily than long
Atmospheric Shielding Due to scattering Dangerous short wavelengths are scattered out to space before making it in
Greenhouse Effect Atmosphere is mostly transparent to visible light and mostly absorptive of infrared EMR Some emitted out, but mostly creates cycle
Greenhouse Effect and Earth Warms Earth to make it habitable (warms ~34 degrees C)
Major Atmospheric Components and Greenhouse Effect DON'T interact w/infrared or contribute to greenhouse effect
Trace Gases and Greenhouse Effect DO contribute
Trace Gases Molecules Polar
Polar Molecules and Greenhouse Effect Polar molecules bind to incoming infrared photons Move faster, generate EM field Absorb passing EMR Raises temperature
Atmospheric Absorption Each gas has its own selective absorption of particular wavelengths Each wavelength is absorbed differently
Water Vapor Primary absorber of CO2
Clouds Reflect incoming sunlight and trap outgoing longwave radiation
High Clouds Warm the Earth
High Cloud Characteristics Wispy, low albedo Absorbs infrared and holds onto it, since they're colder
Low Clouds Cool the Earth
Low Cloud Characteristics White, puffy Dense and high albedo Absorb energy but they're warm so they radiate it back
Net Effect of Clouds Depends on height, temp, droplet size, density, structure
Aerosols Direct Effect Absorb and scatter shortwave radiation Warms atmosphere Cools surface
Aerosols Indirect Effect Nucleation sites for water droplets -> cloud formation

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
