Experimental Global Total Electron Content (GloTEC) Ionospheric Model Available

Experimental Global Total Electron Content (GloTEC) Ionospheric Model Available
published: Monday, August 26, 2024 19:16 UTC
SWPC has released an experimental version of the Global Total Electron Content (GloTEC) ionospheric model.
 
The operational products of the North America Total Electron Content (NATEC) ionosphere model and U.S. Total Electron Content (USTEC) are no longer being supported and will be replaced by GloTEC. GloTEC is a real-time data-assimilative model that provides global electron density and total electron content (TEC). Soliciting comments on the experimental deployment of the GloTEC from users and the general public is through September 23, 2024. Direct access to the experiment products and outputs can be found here.
