If you were to add 1 ppm of CO2 or 1 ppm of methane to the present atmosphere, which would have a bigger effect on the radiation?

What is the skin temperature?

What is the approximate frequency of infrared radiation with a wavenumber of 300/cm (you can also write this as 300cm-1)? You can use a speed of light = 3 x 1010 cm/sec (pay attention to the units).

Looking again at the spectrum shown in the previous question, it is taken from 70 km looking down through the atmosphere. What would you roughly estimate the ground temperature to be? Choose the best answer without any formula or calculation, simply by using the information shown in the graph of the spectrum and looking at frequencies in the atmospheric window.

Why are O2 and N2 not greenhouse gases?

The bare rock model requires that there is a balance between the total energy in and the energy out. Which of the following describes the energy input (in Watts) to the rock? (Isun is the solar radiation in W/m2; r is the radius of the planet; Equation is the albedo)

Looking again at the spectrum shown in the previous question, in the wavenumber range of approximatly 600-700cycles/cm, what is the intensity of the radiation going out to space? Choose the best answer without any formula or calculation, simply by using the information shown in the graph of the spectrum.

What is the meaning of Equation (it has a value between 0 and 1)?

Is the interpretation that the serpent in Genesis 3 represents the devil an example of exegesis or eisegesis?
