| Zusammenfassung |
| Although lightning-generated whistlers have been studied for nearly a century, there
are still questions to be answered. It is clear that, at least in a certain frequency
range, these waves significantly contribute to the overall wave intensity in the inner
magnetosphere. They also influence distribution functions of energetic particles in the
van Allen radiation belts. Due to the on board implemented neural network for
automated whistler detection, the data set obtained by the low-altitude DEMETER
spacecraft allows us to relate measured electromagnetic wave data and energetic particle
flux with the number and dispersion of whistlers detected during a certain time
interval. We distinguish the cases with high and low whistler occurrence and we use
this information to determine the overall effect of lightning-generated whistlers. |
