Climate modeling hw for this exercise you will apply the climate model we derived in class to mercury. you can assume mercury is a perfect blackbody because it has no atmosphere. the closest distance between the sun and mercury is dn-4.6x 10°m. what is the intensity of the sun's light at mercury? 1. 2. mercury has a radius of tmer 2.4 x 10'm. how much power from the sun hits mercury? 3. use the climate model to calculate the average temperature of mercury, given a reflectivity of a 0.07 at this distance, the temperatures reach 700 k during the day at the equator. this compare to your prediction? what could account for the discrepancy? 4. how does mercury has virtually no atmosphere, so the greenhouse effect is not the reason the real temperature exceeds the model. the problem here is that we have calculated an average temperature over the surface of mercury. but, a day on mercury lasts about 2 mercury years, and there is no angle of tilt between the rotational axis and the orbit! 5. what does this say about the temperature during "day" and "night" on mercury? how might you modify the climate model to calculate the daytime temperature (do the calculation if you can)?
