Swarm turns to whistlers and storms
13 April 2018
The batch of new results from ESA's Swarm mission has not only included the highest-resolution map of the magnetic field generated by Earth's crust and a map of the tiny magnetic signals from the oceans, but also, remarkably, some unexpected insight into lightning in the upper atmosphere and geomagnetic storms.
These latest findings are wowing this year's European Geosciences Union meeting in Vienna, Austria. This week-long event draws scientists from all over the world to share discoveries about our planet.
