Evaluation of Techniques to Better Separate and Utilize Astronomical Radio Telescope Signals from those Due to Disturbances in the Ionosphere

Ionospheric disturbances impact radio signals that travel through them.  These ionospheric scintillations are observed across the electromagnetic spectrum using a variety of methods.  Previous studies have demonstrated that signals from radio telescopes can be used to measure and track these disturbances.  Furthermore, a recent study suggests the separation of signals may be enhanced by concurrent measurements of ionospheric disturbances by multiple techniques and at different frequencies.  This study discusses how astronomical and ionospheric signals from radio telescopes have been separated, how that separation might be improved by combining radio-telescope data with data from an alternate measurement methods and how ionospheric signals might be used to characterize ionospheric variability over both long- and short-term time scales.
