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

First-ever mesoscale-resolving fully coupled magnetosphere-ionosphere-thermosphere simulation is published by CGS researchers

Journal of Geophysical Research: Space Physics

Dr. Kevin Pham, a CGS team member from NCAR/HAO, has run the MAGE model fully coupling the magnetosphere, ionosphere and thermosphere, at a resolution allowing it to resolve mesoscales in all relevant domains. This enabled the model to capture localized regions of energy input into atmosphere that caused traveling disturbances observed across the globe by low-altitude satellites. The model was able to capture neutral density perturbations that are responsible for satellite drag and can even cause operators to lose satellites.

Heliospheric version of GAMERA is used to simulate the solar wind at unprecedented resolution

Astrophysical Journal

APL postdoctoral fellow, Dr. Parisa Mostafavi, used the heliospheric version of the GAMERA code to run a solar wind simulation of a Carrington rotation during one of Parker Solar Probe's close encounters with the Sun. Using this very high resolution simulation, Dr. Mostafavi has demonstrated that off-radial velocity shears in the solar wind may potentially be unstable to Kelvin-Helmholtz instability providing a pathway for in situ generation of solar wind turbulence.
