1. Homework Statement
The energy reaching Earth from the Sun at the top of the atmosphere is 1.36x10^3 W/m^2, called the solar constant. Assuming that Earth radiates like a blackbody at uniform temperature, what do you conclude is the equilibrium temperature of Earth?

2. Homework Equations

Stefan-Boltzmann law: R=$$\sigma$$T^4, Wein's displacement law: ($$\lambda$$max)T=2.898x10^-3 mK

3. The Attempt at a Solution

I know that the Earth radiates the same amount of energy it takes in if it is acting as a black body, but I am stuck at figuring out how much energy the Earth is actually absorbing from the sun. If I can figure that out I know what to do with the rest of the problem.
