openAVEM (Open Aviation Emissions)

openAVEM is a Python package that takes a list of flights as input and calculates fuel burn and atmospheric emissions: oxides of nitrogen (NO_x), hydrocarbons (HC), CO, non-volatile particulate matter (nvPM). Landing and takeoff (LTO) is modeled with a time-in-mode approach, while the non-LTO portions of flight (climb, cruise, descent) are modeled using EUROCONTROL's BADA aircraft performance model (which needs to be acquired separately).
