Short summary
We model the structure of the thermosphere for two space weather events that affected satellite orbits. Based on the Sun's irradiation, we simulate atmospheric density profiles and feed them into a model that calculates the influence of precipitating electrons on nitrogen oxide production in the atmosphere. Our results underscore the importance of considering both solar irradiance and particle precipitation to understand and predict space weather effects on the atmosphere and satellite orbits.
