The NCEI Ionospheric Physics Group operates the ionospheric portion of the World Data Service for Geophysics, which seeks out and archives data, products, and information related to the ionosphere. Much of the current effort at NCEI is in the Ionospheric Vertical Incidence Sounding discipline. NCEI leads the effort to collect, provide quality control for, and distribute a unified dataset of vertical sounding scaled parameters using modern dissemination services.
Please note: Ionosonde data is currently unavailable to the public due to processing issues. We are working to resolve the issue as soon as possible, but data may be unavailable for several months. Data will be backfilled once it becomes available. We apologize for any inconvenience.
