From: Swarm accelerometer data processing from raw accelerations to thermospheric neutral densities
Swarm C densities as a function of time and argument of latitude (upper panels) and solar and geomagnetic activity indices \(F_{10.7}\) and \(a_p\) (bottom panels). The left panels show the entire year of data that has currently been processed. The right panels zoom in on the 10 days surrounding the March 2015 St. Patrick’s day geomagnetic storm, indicated by the red arrows in the left panel
