Effective Sunspot Number (SSNI) comparison study

Technical Report ·
OSTI ID:5595614
Report documents the results of a USAFETAC study done to determine whether or not reliable global Effective Sunspot Numbers (SSNis) for the Air Force Global Weather Central's (AFGWC's) Ionospheric Conductivity and Electron density (ICED) model could be calculated based on the present number (11) of digital ionosonde sites. The study found that increasing the number of sites would have a limited effect on ICED output, and that it was feasible to run the ICED model using the present 11-station network, subject to certain limitations.
