Institute for Scientific Research Boston College Seminar Speaker: Dr. Charles (Chuck) Rino, Boston College Visiting Scholar Title: “Global Ionospheric Modeling, Intermediate Scale Structure & Scintillation Theory” When: Tuesday, November 3, 2015, at 1:00pm. Where: Conference Room, ISR, 202 Kenny Cottle Hall, 885 Centre St., Newton Campus. Abstract Over the past three years collaborative analyses of CERTO beacon scintillation data, C/NOFS highresolution plasma density measurements, and theoretical scintillation studies have been pursued. The implicit focus of this activity has been intermediate-scale ionospheric structure, which is the acknowledged source of scintillation. Even so, very little research has been directed toward understanding the evolution of intermediate-scale structure as opposed to the large-scale environment within which intermediate-scale structure evolves. This talk will review new results that suggest a systematic life-cycle evolution of ESF structure. We will argue that in light of these new results and new propagation-theory developments that it is timely and feasible to incorporate intermediate-scale structure as an integral part of global ionospheric model development. We will argue further that this objective can be achieved with a modest redirection of standard analysis procedures and more a challenging improvement of data acquisition and processing software
