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.
