| Zusammenfassung |
| The generation of waves with low frequencies (1-100 mHz) has been observed in the
environment of most bodies in the solar system and well studied at Earth. These waves
can be generated either upstream of the body in the solar wind by ionization of
planetary exospheres or ions reflected from a bow shock or in the magnetosheath
closer to the magnetic barrier. For Mars and Venus the waves may have special
importance since they can contribute to the erosion of the ionopause and by that enhance
atmospheric escape. While over the past years many case studies on wave phenomena
observed at these planets have been published most statistical studies have been
based on magnetic observations only. On the other hand the generation mechanisms
and transport of these waves through the magnetosphere can only be quantified
using both magnetic and particle observations. We use the long time observations of
Venus Express (2006-2014) and Mars Express (2005-2016) and compare to recent
observations by MAVEN to determine the predominant processes and transport parameters. |
