Abstract:
Long-term, continuous recording of VLF (Very Low Frequency) radio noise characteristics at Halley Station, collected under the aims of the VELOX experiment (VLF/ELF Data Logger Experiment). Data captured includes amplitude, polarisation, azimuth arrival bearing, maximum/minimum over ten frequency bands (8 wide, 2 narrow) from 300 Hz to 10 kHz at a 1 s time resolution.
ELF/VLF measurements have been made in various forms at Halley since 1967. VELOX data are compatible with those from earlier loggers at Halley. For a full data description of BAS VLF/ELF data holdings, see BAS VLF/ELF/ULF Data Manual.
