Using Worksheet 3, explore the effects of the Greenhouse Factor (GHF) on your chosen planet. The GHF is a shortcut method of parameterizing the effects of gases on Earth’s surface temperature.   What is the temperature of your planet if GHF = 1.0?   At what value of the GHF will the temperature of this planet be comparable to that of Earth (15°C)? Note: depending on what planet you picked in question 1, you may not be able to obtain a temperature comparable to Earth. If you find that this is the case, provide a brief explanation why.

Question

3) Using Worksheet 3, explore the effects of the Greenhouse Factor (GHF) on your chosen planet. The GHF is a shortcut method of parameterizing the effects of gases on Earth’s surface temperature.

 

What is the temperature of your planet if GHF = 1.0?

 

At what value of the GHF will the temperature of this planet be comparable to that of Earth (15°C)? Note: depending on what planet you picked in question 1, you may not be able to obtain a temperature comparable to Earth. If you find that this is the case, provide a brief explanation why.
