Supporting dataset for "The Role of Propellant Type, Re-entry, and Plume Reactions in the Atmospheric Impacts of Spaceflight"

This is a supporting dataset for “The Role of Propellant Type, Re-entry, and Plume Reactions in the Atmospheric Impacts of Spaceflight”, published in Earth's Future (2026). This dataset contains all data necessary to reproduce the results of the publication.<br>In this work we use trajectory and combustion process modeling alongside publicly available rocket launch data to generate a new emissions inventory for spaceflight emissions in 2022, including the effect of afterburning and re-entry emissions. This inventory is then used with the GEOS-Chem chemistry transport model to provide an estimate of the atmospheric and climate impact of 2022's spaceflight emissions, and the relative effect of different fuels used in spaceflight and afterburning and re-entry processes.<br>Within this repository we provide three types of archives. The HIST_ archives contain files describing two years of atmospheric histories and radiative forcing assessments for specific emission scenarios that were used fin the associated publication, the EMISSIONS archive the emissions inventories generated for this work, and the CODE archive contains the python code necessary to replicate the emission inventories.<br>
