This paper presents an analysis of the atmosphere of Callisto and discusses how the Jovian system molded, and continues to mold Callisto's atmosphere over time. Before the analysis the general properties of Callisto and the atmosphere is reviewed and a literature review of pertinent information regarding the Callisto's atmosphere and previous scientific simulations of the atmosphere. These simulations and observation data for the atmosphere provide a basis for all the parameters used in all of my simulations of the atmosphere. The results of these simulations will provide context on the effect of Jovian plasma on the atmosphere and how the Jovian plasma will continually impact the atmosphere. The source of Callisto's atmosphere and how this source alters over time will also be discussed.
