==Simulation Effects== ===Surface Temperature=== The emissivity of the atmosphere, <math>\epsilon</math>, affects the amount of heat energy that the atmosphere will radiate in all directions, including back down towards the surface of the object. The rate at which energy is added to the object's surface from this [[Atmosphere Heating|atmosphere heating]], or the [[Atmosphere Power]], is estimated as<ref>For example, see: American Chemical Society. [https://www.acs.org/content/acs/en/climatescience/atmosphericwarming/singlelayermodel.html A Single-Layer Atmosphere Model]. ''ACS Climate Science Toolkit: How Atmospheric Warming Works''.</ref> :<math>P_{atm} = f(\epsilon) \sigma T^4 4 \pi R^2,</math> where <math>T</math> is the [[Average Temperature]] of the object and <math>R</math> is its [[Radius]]. The emissivity factor <math>f(\epsilon)</math> depends on the [[Number of Atmosphere Layers|number of opaque layers]] that can represent the atmosphere, <math>N</math>:<ref>For example, see: American Chemical Society. [https://www.acs.org/content/acs/en/climatescience/atmosphericwarming/multilayermodel.html A Multilayer Atmosphere Model].
