Geospace 2d Cut Planes - Pressure

The Geospace Magnetosphere Movies display 2d cut planes of Earth's magnetosphere from the Geospace model output for three different plasma parameters (velocity, density, and pressure). For each plasma parameter, equatorial (x-y plane) and noon-midnight magnetic meridian (x-z plane) cut planes are plotted in GSM coordinates. The animations show the model forecast, where the lead time depends on the solar wind speed, as well as the previous two hours for context.

2D cut planes of the magnetosphere are useful for providing a large-scale, global context of activity in the near-Earth environment. These plots assist forecasters in developing situational awareness and are useful for assessing the validity of the Geospace model. 

For additional space weather products generated using output from the Geospace model, see the following pages:

 

This product uses output generated by the University of Michigan’s Geospace model that consists of several components in their Space Weather Modeling Framework (SWMF). The Geospace model is a first-principles physics based model which includes three components: the University of Michigan’s BATS-R-US magnetohydrodynamic (MHD) model of the magnetosphere; the Ridley Ionosphere electrodynamics Model (RIM) developed at Michigan; and the Rice Convection Model (RCM), an inner magnetosphere ring-current model developed at Rice University.

 

 

The Geospace Magnetosphere Movies represent the first generation of operational space weather products derived from the Geospace model, a model which includes both global and regional short-term predictions of geomagnetic activity. Other operational space weather products generated using output from the Geospace model include the Geospace Geomagnetic Activity Plot and the Geospace Ground Magnetic Perturbation Maps.

 

 

Access to the data will be coming soon.
