Atmospheric Density Inversion Based on Swarm-C Satellite Accelerometer

We used the Swarm-C accelerometer data to invert orbital atmospheric density in this study. First, satellite mission were obtained from ESA’s public platform, and preliminary error correction was performed. This paper refers calibration method of GRACE-A data. It adds linear temperature on original basis. Moreover, study’s results compared with published by ESA. In order explore influence light radiation accelerometer, we established a geometric model simulate physical shape surface. The pressure shadow area judgment established, change acceleration during transition process umbra penumbra then shadowless studied, state analyzed. Finally, drag coefficient calculated based Sentman model. Atmospheric inversion calculations performed using above show spatial distribution at fixed latitude, testing our geomagnetic storms. existing research data, demonstrating effectiveness approach.
