According to satellite observations there is always a net balance between
radiant energy coming in and radiant energy going out.
According to satellite observations there is always a net balance over time between
radiant energy coming in and radiant energy going out from the top of the atmosphere.
That must be so because the Earth (at the top of the atmosphere) quickly arrives at a thermal equilibrium by virtue of the fact that
radiant energy coming in and radiant energy going out both travel at the speed of light.
Not exact matches
Random fluctuations and three physical reasons
come into question to explain this: The model calculations are based on different amounts of
radiant energy from the sun that impinge on Earth's surface and are stored as a result of the greenhouse effect, e.g. due to atmospheric carbon dioxide.
So you will agree that any isotropic gray (defined as: flat spectrum) ball
comes to the temperature related via Stefan Boltzmann to the total
radiant energy impinging on it?
The only things that can change that resultant point of temperature equilibrium are changes in solar radiance
coming in or changes in overall atmospheric density which affect the
radiant energy going out.
5) A warming effect in the atmosphere arises because between
coming in and going out the
radiant energy is «processed» by the molecules in the atmosphere into heat
energy and then back again, often many times for a single parcel of
radiant energy, the number of times being directly proportionate to the density of the atmosphere.
The only things that can change that resultant point of temperature equilibrium significantly are changes in solar radiance
coming in and changes in overall atmospheric density (a function of mass and pressure) which affect the
radiant energy going out or a change in the speed of the water cycle which, because of the unique characteristics of the phase changes of water altering the speed of
energy flow through the system is capable of exerting a powerful regulatory effect.
But do I buy the idea that
energy coming from space environment and leaving to the space environment is all about
radiant energy.
