New method for tracking the movement of ionospheric plasma
A method to track the flow of plasma in the Earth's ionosphere is presented. This takes maps of total electron content (TEC) at various times, and by comparing them derives a map of bulk velocities. The method is a modification...
A comparison of the relative effect of the Earth’s Quasi-D.C. and A.C. electric field on Gradient Drift Waves in large-scale plasma structures in the polar regions
Radio signals traversing polar-cap plasma patches and other large-scale plasma structures in polar regions are prone to scintillation. This implies that irregularities in electron concentration often form within such structures....
Isolating the multipath component in GNSS signal-to-noise data and locating reflecting objects
A filter to separate the effect of multipath in Global Navigation Satellite System (GNSS) signal-to-noise ratio (SNR) data is presented. The filter removes multipath cleanly, and affects neither slowly varying trends (such as...
Polar-cap plasma patch primary linear instability growth-rates compared
Four primary plasma instability processes have been proposed in the literature to explain the generation of phase scintillation associated with polar-cap plasma patches. These are the Gradient Drift, Current Convective and...
Tomographic Imaging of Traveling Ionospheric Disturbances Using GNSS and Geostationary Satellite Observations
Abstract Traveling ionospheric disturbances (TIDs) are the manifestations of atmospheric gravity waves in the ionosphere. These disturbances have practical importance because they affect satellite navigation technologies such as...
