| 41. | During the 2010 eruption of Mount Merapi, DEMETER noted anomalies in the ionosphere.
|
| 42. | After the end of the Second World War the ionosphere research continued until 1946.
|
| 43. | It is now known that in fact the waves are reflected by the ionosphere.
|
| 44. | This is especially useful in determining the free electron content of a planetary ionosphere.
|
| 45. | Within it lie layers of increased electron and ion density that form the ionosphere.
|
| 46. | :I would expect that multiple nuclear detonations in the ionosphere would be needed.
|
| 47. | It's in the ionosphere, in rushing streams, in air we breathe.
|
| 48. | With VLF waves, the Ionosphere and earth's surface act as a waveguide.
|
| 49. | Mediumwave and shortwave reflect off the ionosphere at night, which is known as skywave.
|
| 50. | As of 2008, the parameters of the ionosphere of Ganymede are not well constrained.
