Announcing Geospace Model Version 1.5

Geospace delta B North America example product
Announcing Geospace Model Version 1.5
published: Wednesday, November 08, 2017 21:34 UTC

The Geospace products: Geospace Geomagnetic Activity Plot, Geospace Ground Magnetic Perturbation Maps, and Geospace Magnetosphere Movies that are available on the Space Weather Prediction Center website are driven by the Geospace Model, which was upgraded to Version 1.5 at 1000 MT November 8, 2017. The products and the interface to the model, that have been available since October 2016, remain the same; however, working with model developers at the University of Michigan, minor changes have been implemented that will improve model performance today and lead to new products in the future. Further details of these changes can be found on each Geospace product web page's history tab, as routed to by clicking the aforementioned product links; or by navigating to via "Products and Data" and the “Models” dropdown list from our SWPC webpage.
