This article is a response to a claim about the positive feedback of water vapor on the total emissivity of the carbon dioxide related to the overlap of absorption-emission bands. I have taken into consideration the total altitude of the atmosphere, answering to another erroneous claim on the sense of including the total path length of the irradiance from the surface. In addition, I have calculated the effect of the carbon dioxide in the temperature of the atmosphere of Mars for demystifying the concept of the carbon dioxide as a warming gas.
When I presented my article on the Total Emissivity of the Carbon Dioxide and its Effect on the Atmospheric temperature
, the main criticisms were on the sense that I had not considered the overlapping absorption and emission bands of the carbon dioxide and the water vapor, as well as the length that I had introduced for making my calculations which, according to those criticisms, it should be 7000 m, which is the altitude of the atmosphere at which the proportion of the gases in the air mixture is more or less uniform, instead 1 m.
I have acceded to those claims and introduced the altitude of 7000 m in the algorithms for calculating the total emissivity of the mixture of water vapor and carbon dioxide in the atmosphere.
In the other hand, there were claims against my decision to obtain the total emissivity of the carbon dioxide alone, when they claimed that the water vapor worked like a positive feedback that enhanced the total emissivity of the carbon dioxide in the region of the emissive spectrum where the emission bands of the carbon dioxide and the water vapor overlaps. I assented to make the calculi for obtaining the amount of total emissivity that the water vapor causes on the total emissivity of the carbon dioxide, precisely there, where the emission bands overlap.
