High-resolution modeling of aviation emissions in Norway.

Emissions from aviation contribute increasingly to both air pollution and climate change. Understanding how these emissions are distributed across regions, seasons, and different altitudes is important to fully ascertain the climate impacts caused by our current aviation sector and set a clear benchmark for our mitigation efforts. The Aviation Transport Emission Assessment Model (AviTEAM) is developed for this purpose. The model estimates various emission species from aviation activities based on flight trajectories, airplane, engine types, and atmospheric conditions. In this paper, we present the AviTEAM framework and apply it to study the emissions from commercial aviation in Norway. We find emissions associated with Norwegian air transport for 2019 of 4.5 Mt CO 2 , 26.2 ktNO x , 3.26 ktHC, and 1.8 ktCO. Furthermore, we exemplify how Automatic Dependent Surveillance-Broadcast data in combination with flight dynamic and emission models can be used to generate high-resolution geospatial emission datasets for research and national reporting purposes. • Provides an updated aviation emission inventory for Norway. • Uses Automatic Dependent Surveillance-Broadcast data for activity modeling. • Assesses each flight with aircraft type and engine-specific modeling. • Shows the distribution of fuel consumption and various emission species. • Concludes that the approach informs the scientific and other audiences.
