At our distance from the Sun, the intensity of solar radiation is 1370 W/m2. The temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the ef- fect of absorption of infrared light emitted by the surface so as to make the surface temperature of the Earth higher than if it were airless. For comparison, consider a spherical object of radius r with no atmosphere at the same distance from the Sun as the...

The surface of the Sun has a temperature of 5500 ∘C. Treat the sun as a perfect blackbody with an emissivity of 1.0 and a radius of 7.0*10^8 m. Given; the temperature of space is 3.0K and the power that it takes for the sun to radiate into space is 3.9 * 10^26 W. The solar constant is the number of watts of sunlight power falling on a square meter of the Earth's upper atmosphere. Calculate the solar constant given...

The total power consumption by all humans on earth is approximately 1013 W. Let�s compare this to the power of incoming solar radiation. The intensity of radiation from the sun at the top of the atmosphere is 1380 W/m2. The earth's radius is6.37�106 m. What is the total solar power received by the earth? By what factor does solar power received by the earth exceed the total human power consumption?

At our distance from the Sun, the intensity of solar radiation is 1370 W/m^2 . As discussed in class and in the textbook, the temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the effect of absorption of infrared radiation by the surface so as to make the surface temperature of the Earth higher than if it were airless. The average global surface temperature of the Earth is ~288 K. Calculate the surface...
