Lina Zafer Hadid, a postdoctoral researcher at IRF in Uppsala, has published an article in Physical Review Letters estimating how much energy is transferred from large to small scales in the Earth's magnetosheath, the boundary between the charged particles coming from the sun and the magnetic bubble that protects our planet. The study, based on Lina's PhD work, uses measurements made from the European Cluster and the American Themis spacecraft orbiting the Earth. Lina is the lead author of the article that for the first time is able to quantify the role that turbulence plays in this energy transfer.

The Swedish Institute of Space Physics (IRF) is a governmental research institute which conducts research and postgraduate education in atmospheric physics, space physics and space technology. Measurements are made in the atmosphere, ionosphere, magnetosphere and around other planets with the help of ground-based equipment (including radar), stratospheric balloons and satellites. IRF was established (as Kiruna Geophysical Observatory) in 1957 and its first satellite instrument was launched in 1968. The head office is in Kiruna (geographic coordinates 67.84° N, 20.41° E) and IRF also has offices in Umeå, Uppsala and Lund.
