New Experimental Regional Geomagnetic Products Available

New Experimental Regional Geomagnetic Products Available
published: Monday, November 07, 2016 14:22 UTC

SWPC deployed experimental products from the new operational Geospace model on Oct 5th. This model provides short-term guidance of the state of Earth’s magnetosphere using real-time solar wind data and F10.7, a solar EUV proxy, as input. The model also provides for the first time regional guidance of geomagnetic activity. Multiple product web pages are available including: a Global Geomagnetic Activity Plot, Equatorial and Meridional Magnetospheric Views and Ground Magnetic Perturbation Maps. The Global Activity Plot provides recent history of geomagnetic activity along with a short term (15-45 minutes)  prediction of upcoming activity.  The Equatorial and Meridional Views of the Earth's magnetosphere show graphical output for three different plasma parameters (velocity, density, and pressure). These graphic cut planes of the magnetosphere are useful for providing a large-scale, global context of geomagnetic activity in the near-Earth environment.  The Ground Perturbation Maps display the gridded magnetic variations on a five by five degree global grid. These maps are useful for providing regional disturbance predictions that can be used by power grid operators to determine if disturbances are likely to have impacts at their general location. All three pages are currently hosted on our experimental products pages for customer evaluation before being promoted formally to operations. Promotion to operations is planned for early 2017. Comments on this new model and its products can be provided at SWPC's feedback page.
