LEAT Space Launch Emission Inventory 2019 - 2025

The dataset includes the Global Space Launch Emission Inventory (GSLEI) for space launches 2019 - 2025 calculated with the Launch Emission Assessment Tool (LEAT) (see also github.com/lcasts/leat).It contains the -input_data (Launch vehicle database, launch site database, launch scenario database as well as the config.py)-ouput_data (Emission profiles for each year and Emission Factor, CEA Equilibrium and CEA Frozen calculation methodology and different x_ab uncertainty factors). A description of the tool is given at:Fischer, J.-S., Fasoulas, S., Nützel, M., and Schmidt, A.: Launch Emission Assessment Tool (LEAT v1.0): Part I – Development of a tool to calculate altitude-dependent rocket launch emissions for use in chemistry-climate models, EGUsphere [preprint], https://doi.org/10.5194/egusphere-2026-3050, 2026.
