On the ground or in the atmosphere? Swarm satellites help characterize and pinpoint destructive events

Phys · · 405 words · By Alka Tripathy-Lang

The article describes the Swarm-AWARE project by the European Space Agency, which uses Swarm satellites and other data to distinguish between space weather effects and natural hazard signals. It highlights the potential for these findings to improve infrastructure protection and early-warning systems, citing the 2022 Hunga Tonga eruption as a case study.
