Is Diffuse Aurora Driven from Above or Below?
Presented by George Khazanov
NASA Goddard Space Flight Center

Thursday, October 18, 2018
11:00 A.M. in 169-336

The aurora is one of the most important and fundamental phenomena in space physics, related to the interaction of the solar wind with the planetary magnetospheres of Earth, Jupiter, and Saturn. We demonstrate that wave particle interaction processes that drive precipitating fluxes in the region of diffuse aurora from the magnetospheric altitudes are only the first? step in the formation of electron precipitation at ionospheric altitudes, and they cannot be separated from the atmospheric "collisional machine" that redistributes and transfers their energy inside the magnetosphere-ionosphere-atmosphere coupling system.
