Outline Notes for Lecture 4 Review Questions from previous lecture Matching: 1. Radiation being bent 2. Radiation being scattered downward 3. Radiation being redirected by gases and dust 4. Passage of energy through the atmosphere and water 5. Shorter visible lightwaves being scattered 6. Mirages 7. Longer visible lightwaves being scattered 8. All visible lightwaves being scattered A. Eight additional minutes of daylight B. Diffuse radiation C. Sky is blue D. Refraction E. Sunsets F. Transmission G. Smog H. Scattering Albedo involves: A. refraction B. reflectivity C. diffuse radiation D. scattering of thermal energy Which has the highest albedo? A. White sand B. Water where the sun is directly overhead C. A forest D. dark asphalt highway Which is not true regarding albedo? A. Darker colors absorb more insolation B. Low sun angles over water produce higher albedoes than high sun angles C. Smooth surfaces have higher albedo than rough surfaces D. The Earth’s albedo is sometimes called Earthshine E. The Earth has a lower albedo than the moon does. T/F When clouds prevent insolation from reaching the ground, it is known as cloud-albedo forcing. T/ F When clouds trap longwave radiation from earth, which raises temperatures, it is known as cloud- greenhouse forcing. T/F After Mount Pinatabu exploded, global temperatures went up. When reduced amount of light reaches the earth’s surface, often due to pollution, it is called: A. Global dimming B. Aerosol dimming C. Earth’s human albedo factor D. Global darkening

Absorption is: 69% of the insolation we receive is absorbed. 45% of insolation is absorbed by __________________ 24% of insolation is absorbed in __________________________ Absorbed energy is converted into either___________________________(especially thermal infrared) or _____________________ (through photosynthesis by plants) Sample question: Which is false? A. More insolation (energy) is absorbed by the atmosphere than by land and water
