7th Brazilian meeting on space geophysics and aeronomy
Editor(s): Igo Paulino, Inez Batista, Fabiano Rodrigues, Marcos D. Silveira, and Christoph Jacobi
We invite researchers to contribute to the special issue "7th Brazilian meeting on space geophysics and aeronomy" by submitting papers of recent research in the field of space science and aeronomy. This issue covers a wide range of aspects of Sun–Earth relations, which include space weather, heliophysics, magnetospheric and upper atmospheric physics and processes, and dynamics and structures of the neutral atmosphere. The issue will contain proceedings of the 7th Brazilian meeting on Space Geophysics and Aeronomy that was held in Santa Maria/RS, Brazil, from 5 to 9 November 2018, but other manuscripts are also welcome.
