Title: Swarm measurements of upper atmosphere density during two geomagnetic storms

Description: Comparison of upper atmosphere neutral density observations, derived at TU Delft, from the orbit information provided by the GPS receiver on-board the Swarm A and Swarm B satellites. The plots show the considerable increase in density, and therefore satellite drag, during the two largest storms of 2024.
