Ionospheric signals from sub-ionospheric radio transmissions on 2016 August 27

Data collected from a wideband radio receiver in Bath, UK was analysed to obtain ionospheric signals from narrow band sub-ionospheric radio transmissions. The transmissions analysed in the dataset are callsigns GBZ (19.58kHz), GQD (22.1kHz), DHO (23.4kHz) and MSF (60kHz). The ionospheric signals reveal perturbations in the ionosphere along the propagation paths of the transmissions during the period of measurement on 2016 August 27. The dataset includes the processed ionospheric signals in Matlab binary format together with scripts that were used to obtain the ionospheric signals from the raw radio data.
