Cyclone tracks for the region south of 60S for 1979 - 2018, derived by applying the University of Melbourne cyclone tracking software to ECMWF ERA-Interim reanalysis MSLP fields at 6-hourly temporal and ~1.125 degree spatial resolution.

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.
