My understanding is that the earth’s atmosphere was originally formed by the molten earth itself, and the sun was 70% weaker that present. Then as the earth cooled the energy required to keep the atmosphere up against the force of gravity was provided by incoming solar radiation.
Presumably this energy is in excess of that incoming from the sun and outgoing to space. Can anyone tell me how much solar energy is required to kind of keep the sky up.
So say we started with the present sun and current atmospheric mass with the earth at its blackbody temperature with the current solar energy hitting its surface - 255K. How much additional solar energy is required to lift those gasses not already off the ground at this temperature up into the sky?
I realise that the current energy reaching the earth’s surface is due to the atmosphere absorbing some of the energy but I’m interested in the excess energy in the earth/atmosphere system required to keep the atmosphere up.
