Tomographic imaging of a large-scale travelling ionospheric disturbance during the Halloween storm of 2003
The most intense ionospheric storm observed in recent times occurred between 29 and 31 October 2003.The disturbances to the Ox Bows high-latitude regions set off several large-scale travelling ionospheric disturbances (LSTIDs), wave-like perturbations in the ionospheric electron density.This paper investigates one particular TID on 31 October 2003
