This linux package is a VLF receiver for monitoring VLF transmitter signals for evidence of transients indicating ionospheric disturbances. It takes sample pairs from dual-channel sound cards and spectrally processes them to Stokes parameters.

Features

  • Acquires two polarizations from loop antennas via a sound card.
  • Time plots of Stokes parameters, X/Y polarization amplitudes and relative phase, ellipse major and minor axes and orientation, normalized parameters, GOES x-ray flux, and SWPC event start-peak-stop times.
  • Scatter plots of pairs of parameters.
  • Utilities for downloading GOES x-ray data, downloading SWPC events data, and a front end for generating plots (in Bash).

Project Samples

Plot of the four Stokes parameters. Scatter plot of Stokes U and V. Normalized Stokes parameters with GOES x-ray flux.
