Understanding ion heating in Earth’s magnetosphere using energetic neutral atom imaging

Ions are heated and transported throughout the magnetosphere during geomagnetic storms. Using energetic neutral atom imaging, we are able to calculate global ion temperature “maps” to study where these hot ions are and how they move. I will present our ion temperature calculation technique, what we’ve learned about ions during storms, and how we’re using these temperatures to improve modeling of the magnetosphere. In particular, I will discuss ongoing work on the injections of ions from the magnetotail to the inner magnetosphere.
