Inverse modeling of ionospheric irregularities observed using GPS scintillations at Poker Flat, AK

Scintillations in the Global Navigation Satellite System (GNSS) signals are rapid variations in their amplitude and phase resulting from electron density irregularities in the ionosphere, can be used to study the ionospheric irregularities. We utilize Global Positioning System (GPS) scintillation measurements from scintillation auroral GPS array (SAGA) at the Poker Flat Research Range (PFRR) (Datta-Barua et al., 2015), Alaska on 8 December 2013 in conjunction with ancillary multi-instrument observations combined with physical parameters derived from a forward propagation model, and an inverse method to achieve an improved understanding of the physics of the irregularities and the processes that may produce them.
