Abstract:<br>
Michael Buonsanto was an early leader in ionospheric storm studies. He possessed a remarkable talent for synthesizing scientific insights from a diverse array of measurements and instruments. His work rested on three key pillars: scientific collaboration, innovative
analysis techniques, and the integration of observations with modeling and theory. He organized numerous community workshops on this topic and published a seminal paper, “Ionospheric Storms, A Review” (Buonsanto 1999). Michael’s pioneering research was instrumental
in identifying large mid-latitude electron density gradients associated with ionospheric storms—a precursor to the significant recognition of the space weather impacts associated with ionospheric storms that occurred when the FAA’s WAAS system became operational
in 2003. <br>
<br>
This lecture by Anthea Coster will explore the remarkable progress made over the past 25 years in understanding ionospheric storms, driven by advances in instrumentation, measurement methodologies, and ionospheric modeling. It will highlight the growing importance
of space weather research and offer a reflective overview of developments in radio remote sensing instrumentation and data analysis techniques, emphasizing the enduring influence of Michael’s contributions. Finally, the lecture will look ahead to the opportunities
and challenges that await the next generation of space weather research.<br>
