Description

The CHAMP (CHAllenging Minisatellite Payload) satellite was a highly successful German Low Earth Orbit (LEO) mission that operated for more than ten years (2001 – 2010), providing high precision gravity and magnetic field measurements. Due to its almost circular and near-polar orbit it was able to achieve homogeneous and complete global coverage of the Earth's sphere, with orbit and magnetometer measurements, thus enabling many studies in a wide variety of fields. Starting from our wavelet-based spectral analysis methods, which we have applied extensively on CHAMP magnetic field data, we have developed an automated tool for the detection and classification of Pc3 and low frequency Pc2 wave events. The creation of a database of such events enabled us to derive valuable statistics for many important physical properties relating to the spatio-temporal location of these waves, the wave power and frequency, as well as other parameters and their correlation with solar wind conditions, magnetospheric indices, electron density data, ring current decay and radiation belt enhancements. This work has received funding from the European Union under the Seventh Framework Programme (FP7-Space) under grant agreement n 284520 for the MAARBLE (Monitoring, Analyzing and Assessing Radiation Belt Energization and Loss) collaborative research project.
