 So this is another view of the same simulation where we simply don't have quite as many dots showing all of the photons. It makes it a little bit easier to see what's going on. Again, the yellow photons are the visible light coming down from the sun, most of which make it all the way down to the ground. Some of them bounce off the clouds and go directly back into space. The infrared photons are created by the ground when the visible light warms the ground up. Some of them are able to escape off into space. Some of them are absorbed in the atmosphere and redirected back down to the ground. Some of them are absorbed in the clouds and redirected back down to the ground. If I remove the clouds, again I get more of the visible light coming down to the surface. And I still have some of the infrared photons being directed back down to the ground.
