    "description": "This dataset contains 5 s average phase and amplitude data from VLF radio wave communication transmitters received on two subionospheric propagation paths. The first is the path from NPM (Hawaii, 21.4 kHz, 21.4\u2070N, 158.2\u2070E), recorded at the field-site for New Zealand's Scott Base, Arrival Heights, in Antarctica (77.8\u2070S, 166.8\u2070E). The propagation path is ~11 Mm long, oriented nearly north-south, with the mid-point at 28.9\u2070S, 164.4\u2070W. The second is from NAA (Culter, Maine, USA, 24.0 kHz, 44.7\u2070N, 67.3\u2070E), and recorded at Sodankyl\u00E4 Geophysical Observatory (Lapland, Finland, 67.4\u2070N, 26.4\u2070E). The propagation path is ~6 Mm. Both VLF recievers are UltraMSK software defined radio systems connected to magnetic field sensing loops.\n\nThe data files are formatted as ASCII text files with columns of time (s), amplitude (dB) & phase (degrees) data. The MATLAB script plotUltraMSK.m can be used to plot the data files and an example data plot has been included in the dataset.\n\nFurther details provided at:\nBelcher, S. R. G., Clilverd, M.
