Problem 2
What is the wavelength range, in \(\mu \mathrm{m}\), for infrared light? In what portion of this range does the Earth receive IR from the Sun? What are the wavelength limits for the thermal IR range?
Problem 3
Explain in terms of the mechanism involved what is meant by the greenhouse effect. Explain what is meant by the enhancement of the greenhouse effect.
Problem 4
Explain what is meant by the terms symmetric and antisymmetric bond-stretching vibrations, and by angle-bending vibrations.
Problem 5
Explain the relationship between the frequency of vibrations in a molecule and the frequencies of light it will absorb.
Problem 7
What are the two main anthropogenic sources of carbon dioxide in the atmosphere? What is its main sink? What is fixed carbon?
Problem 8
Is water vapor a greenhouse gas? If so, why is it not usually present on lists of such substances?
Problem 9
Explain what is meant by positive and negative feedback. Give an example of each as it affects global warming.
Problem 10
What is meant by the term atmospheric window as applied to the emission of IR from the Earth's surface? What is the range of wavelengths of this window?
Problem 11
What reaction is the dominant tropospheric sink for methane?
Problem 12
What are four important trace gases that contribute to the greenhouse effect?
