SitatWillis, please consider this: You have an atmospheric layer made up 100% of nitrogen, oxygen and argon. It holds a physical temperature of 255K. Apply the S-B equation to derive the radiative flux emitted by this layer. Then add some water vapour and carbon dioxide so that the air layer now contains ~99.5% N, O and Ar and ~0.5% H2O and CO2. The layer is still at 255K. Now apply the S-B equation to derive the radiative flux. Is the layer in the former condition able to emit a perfect BB flux based solely on its physical temperature? Is the layer in the latter condition able to emit a perfect BB flux based solely on its physical temperature?Does the emissivity of an air layer going from 100% N, O and Ar to 99.5% N, O and Ar + 0.5% H2O and CO2 go from 0 to 1?
