Emission attribution to airplane trajectories
Current aviation related emission inventories are outdated. Moreover, the latest inventories have been calculated on the basis of declared turbine emission behavior, which is – as our latest research found out – different from real-life conditions. Climate, but also atmospheric chemistry and local air quality modelling studies therefore suffer from the false information, leading to non-negligible uncertainties in the results. Using ADS-B and FLARM trajectories, and linking those trajectories to real-life emission measurements performed with SMARTEMIS, a world-wide emission inventory can be calculated.
We’re offering following subjects to master students looking for a VT or MT topic:
- Thrust setting model: Create a model describing the thrust setting of an airplane based on trajectory and meteorological data as well as statistical information about its weight.
- Emission calculation per trajectory: Per trajectory, based on correction factors and our own measured emission data for the most important engine types, a per-trajectory-emission can be calculated.
- Upscaling to the Swiss territory: This task is based on task (1), where ADS-B and FLARM-based trajectories will be used to generate a Swiss-wide emission inventory. This includes a significant amount of big-data coding.
- Upscaling to the entire world: Based on world-wide trajectories, (3) is upscaled to the entire globe, therefore generating a new aircraft emission inventory.
