Swarm and Cluster Get to the Bottom of Geomagnetic Storms

The magnetic field and electric currents in and around Earth generate complex forces that have immeasurable impact on every day life. The field can be thought of as a huge bubble, protecting us from cosmic radiation and charged particles that bombard Earth in solar winds. (Credit: ESA/ATG medialab)

PARIS (ESA PR) — The notion of living in a bubble is usually associated with negative connotations, but all life on Earth is dependent on the safe bubble created by our magnetic field. Understanding how the field is generated, how it protects us and how it sometimes gives way to charged particles from the solar wind is not just a matter of scientific interest, but also a matter of safety. Using information from ESA’s Cluster and Swarm missions along with measurements from the ground, scientists have, for the first time, been able to confirm that curiously named bursty bulk flows are directly connected to abrupt changes in the magnetic field near Earth’s surface, which can cause damage to pipelines and electrical power lines.

NOAA Launches Crowdsourcing Competition for Better Forecasting of Magnetic Field with DrivenData and HeroX

$30K in Prizes for Improvements of Current Models to Provide Advance Warning of Geomagnetic Storms and Reduce Errors in Navigation Systems

Boulder, Colorado — December 15, 2020 — The National Oceanic and Atmospheric Administration (NOAA) in partnership with the NASA Tournament Lab today announced its crowdsourcing challenge, “MagNet: Model the Geomagnetic Field”. The challenge, which is being implemented by DrivenData and HeroX, seeks to mitigate the impact of geomagnetic storms on navigation systems through improved forecasting by increasing the accuracy in real-time magnetic field modeling and reducing errors in the magnetic navigation systems.
