Surface Temperature of Earth from Black Body Radiation and the Stefan-Boltzmann Law

[@daphnekarolinaa]

Thank you. It helped me to understand the efficient temperature in a book of astrobiology, I like to see where the equations come from.

A minor temperature raise raises the emissivity really a lot. That's a bit puzzling at first sight since this suggests that the energy output raises also to the fourth power. But then the input must follow that. So I could think that it takes much more energy to raise the temperature from 600 K to 610 K than to raise a body of 400 K to 410 K.

A very simple and good lecture ❤

Because the Earth is a sphere, you need to have a distribution equation. Use the mathematics from NASAs lunar diviner experiment. You have to take into account the angle of incidence. It’s interesting how the earth and the moon are very similar when you take into account the size and speed of rotation. It makes the greenhouse effect disappear.

Hello Scott I'm probably being too simplistic but are you saying we can work out the temp of the earth by using the SB Law?

Yes
