Minimize Overview
Observations show that geomagnetic field lines follow closely the atmospheric circulation patterns and that geomagnetic field variations are precursors to climate change. Therefore close monitoring of the local and global geomagnetic field variations by satellite systems will assist prediction of hurricane tracks, intensification and also long-term weather trends.

Unravelling Earth's magnetic field

21 March 2017

ESA's Swarm satellites are seeing fine details in one of the most difficult layers of Earth's magnetic field to unpick - as well as our planet's magnetic history imprinted on Earth's crust.

There's a jet stream in our core

19 December 2016

We would normally associate jet streams with the weather but, thanks to ESA's magnetic field mission, scientists have discovered a jet stream deep below Earth's surface - and it's speeding up.

Magnetic complexity begins to untangle

22 June 2015

After a year in orbit, the three Swarm satellites have provided a first glimpse inside Earth and started to shed new light on the dynamics of the upper atmosphere - all the way from the ionosphere about 100 km above, through to the outer reaches of our protective magnetic shield.
