This National Science Foundation (NSF) Project Grant award under the Geosciences Program (CFDA 47.050) provides $359,725 to the University of Texas at Dallas (UTD) to conduct collaborative research on the equatorial ionization anomaly (EIA) in the American sector. The key objectives are to:
(a) Explore the variability of the interhemispheric asymmetry (IHA) of the EIA over multiple solar cycles and elucidate its physical mechanisms.
(b) Unravel the mechanisms driving the significant IHA of the post-sunset EIA in the American sector and its correlation with ionospheric scintillation activity during sudden stratospheric warming (SSW) events.
The research methodology involves analyzing total electron content (TEC) data from ground-based GNSS receivers and conducting NCAR TIEGCM simulations to investigate the influence of lower atmospheric forcing on IHA variations. This 3-year project, starting Jan 1, 2025, aims to advance the understanding of EIA variability and its impacts on global communication and navigation systems.
