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

CGS is supported by NASA under Cooperative Agreement 80NSSC22M0163.

MAGE simulation reveals a possible cause of the Starlink satellite loss early this year

Space Weather

Dr. Dong Lin, a CGS team member from NCAR/HAO, has investigated the variation of thermospheric neutral density during the 3-4 February 2022 geomagnetic storm, when about 40 Starlink satellites were lost after they launched. Using the whole geospace model developed at CGS, MAGE, Dr. Lin simulated the SpaceX storm event and compared with available satellite measurements and other ionosphere-thermosphere models. Dr. Lin found that empirical and standalone ionosphere-thermosphere models either underestimated the storm enhancement or could not resolve the gradual recovery of thermospheric density, a limitation attributed to less reliable characterization of magnetospheric inputs to the ionosphere-thermosphere. This study highlights the importance of fully coupled whole geospace models in space weather studies.

The 3rd CGS Workshop was a success!


The 3rd CGS Workshop was held at JHU/APL and virtually on November 14-15, 2022. The workshop agenda is available here. Zoom recordings and slides have been posted and linked from the agenda webpage. The details of the previous two workshops, including recorded presentations, can be found on the CGS "News and Event" page.
