Part C: The Earth’s atmosphere can be considered to be a heat engine, in the Carrot (thermodynamic) sense. The temperature at top of the upper atmosphere is that necessary to radiate infrared energy back into space so to balance that gained from the sun. The surface is heated by the sun and insulated by the atmosphere (the greenhouse effect) so it’s warmer. 1) What is the efficiency of this heat engine if the air at Earth’s surface is 288 K...

A model cost/benefit analysis of solar power. The main ingredients of this analysis are the power used (required) and the power delivered. For a simple model we want to use broader averages. Used: An American home has an average power use of 1.2 kW. That means that considering all of the daily variation, the difference between night and day and the seasons, etc., the average at any given second is 1.2 kJ per sec = 1.2 kW. Delivered: The home...

This is from Principles of Planetary Climate, Problem 1.13 The thick CO2 atmosphere of Venus is nearly opaque in the infrared, so observations of Venus in the infrared spectrum provide no direct information about the temperature of the ground. However, the atmosphere is nearly transparent to microwave radiation, so the microwave emission of the planet can be used to infer its surface temperature. Indeed, this is how it was inferred in the 1960s that the surface of the planet was...
