Based on measurements of the magnetometer MPO-MAG on board the spacecraft BepiColombo on its way to Mercury, we present a statistical overview on Alfvénic structures in the interplanetary magnetic field (IMF) in the inner solar system between approx. 0.3 – 1 AU and their implication on the offset calibration accuracy of space-borne magnetometers.
Different properties of the Alfvén waves are examined and statistically compared to each other, as are for example: orientation of the wave plane, orientation of the main magnetic field.
In addition to the spatial properties, the temporal properties like stability, occurrence rate and typical timescales of Alfvén Waves are also studied.
To highlight possible differences of the IMF between the inner Solar System and at Earth-distance, results are then compared to measurements of the Moon-orbiting ARTEMIS probes.
