Geospace Storms

Transforming the Understanding and Predictability of Space Weather


space weather modeling

We innovate community space weather modeling capabilities by developing a mesoscale-resolving, data-augmented, seamlessly coupled Multiscale Atmosphere-Geospace Environment (MAGE) model


the scientific, academic, operational and broader public communities

We empower these communities by supporting NASA missions and facilitating a vibrant MAGE-enabled research program beyond CGS; laying the groundwork for transitioning MAGE to operations; training a new cohort of interdisciplinary geospace scientists; and engaging diverse audiences and expanding public awareness of space weather.


together how stormtime geospace responds to solar disturbances

We discover how different parts of geospace work collectively during storm time to shape its responses to solar disturbances
