Web1 okt. 2016 · About this book Over a half century of exploration of the Earth’s space environment, it has become evident that the interaction between the ionosphere and the magnetosphere plays a dominant role in the evolution and dynamics of magnetospheric plasmas and fields. WebIt will be one task of this test phase to gather first experience with operational ionosphere processing and to allow those Analysis Centers, which need more time to become operational, to keep connected to the “IGS ionosphere train”. New combination strategies and software can be tested in this phase.
