AB: In the past four or five years a concerted effort to predict and understand the rate at which Mars is losing it ionosphere, thus it's atmosphere, has been underway. These efforts are simulations efforts and entail both MHD and kinetic simulations. This paper will present our most recent efforts to improve the predictions and test the models being used in the predictions. The tests to be presented cover topics such as numerical resolution issues, ionospheric model issues, the differences found when using ionospheric profiles or creating the ionosphere via solution of chemistry equations. The affect of these various tests on the predicted loss rates will be presented as well as topographic changes in variables such as the global electric field structures.
