Heat, Gravity and Temperature Distribution of Earth, Mars and Venus

Authors: Emil Junvik

Abstract The vertical mean temperature distribution and gravity are coupled to the power of total solar irradiance. A simple geometrical modification of the two-dimensional surface of the blackbody combined with a hemispherical solar irradiation is presented as an explanation of surface temperature. Radiative heat transfer is shown to explain effective temperature and troposphere temperature. The difference between the effective temperature of the perfect blackbody and the observed effective temperature, is found to match the energy needed for the force of gravity when expressed in units of thermal resistance, stress and pressure. The power source strength needed for the effective temperature to be radiated from the atmosphere is shown to be equal to a core temperature of 5770K by using the inverse square law. Altogether this combines to a basic framework of energy distribution inside the system of Earth. It is simply an extension to the blackbody model into a more realistic definition with absorption in depth of a volume, which inevitably leads to a fraction of the heat to be turned into work. It is a suggestion for a new approach of understanding how solar radiation interacts with the planet. The method is used to analyze temperature distribution on Mars which confirms it as a useful model, although with some differences in the results. Venus, with its deep atmosphere, show similar correlation to spherical volumetric distribution, but all three planets have different relationships to Solar Irradiance. Altogether it is shown in this paper that on a bulk scale energy is what dominate the structure of the three planets independently of mass.
