Commercial Space Vehicle Emissions Modeling 25 3 Emissions Modeling Methodology The purpose of the commercial space vehicle emissions model is to enable users to produce emissions estimates that are relevant to environmental analyses. Figure 17 shows an overview of the emissions modeling methodology that was developed to achieve this goal.

Commercial Space Vehicle Emissions Modeling 26 Emissions indices are the factors that relate the amount of propellant burned to the amount of pollutants emitted by a rocket engine. Thus, the emissions indices are required by the commercial space vehicle emissions model to produce the emissions inventory output.

Commercial Space Vehicle Emissions Modeling 27 3.3 Emissions Model Calculations The commercial space vehicle emissions model calculates the mass of propellant burned and the mass of each pollutant emitted by commercial space operations. The calculations are first performed at the most detailed level, and the detailed results are then aggregated to produce the propellant burn report and emissions inventory.

Commercial Space Vehicle Emissions Modeling 28 The reporting options and terminology for the propellant burn report and emissions inventory were adopted from AEDT. As in AEDT, the results may be grouped by the following options: The Operations Detail report lists the results by events (i.e., individual flights)
