I'm recently studying heat transfer processes. I saw that the heat current emited by a radiating body is given by:

[tex]\frac{dQ}{dt}=H=A e \sigma T^4[/tex]

I was wondering how to calculate the H from the sun to a unit area here on earth. How should I do it? I've seen exercises where they use this formula and for A they use the area of the body in question, but they never do it like:

What H from the sun do we recieve here on earth? I guess it's not the same being on the surface of the earth and being on that of the sun, right?

Thanks!
