Equatorial scintillation predictions from C/NOFS Planar Langmuir Probe electron density fluctuation data

Abstract

Data from the Planar Langmuir Probe onboard Communication/ Navigation Outage Forecasting System will be combined with coherent scatter radar and scintillation measurements to analyze the performance of different propagation models of satellite signals. This work will characterize: (i) the prediction capability of a purely spacebased phase-screen scintillation model in comparison with another that represents the variation of the irregularity strength along ray paths in detail; and (ii) how early in time it is possible to detect irregularity structures, estimate their temporal and spatial evolution and predict their effects on propagation through different ionospheric regions at later instants of time.
