VELOX
Listed in NASA Earthdata CMR
Description
Data from the VELOX (VLF/ELF Logger Experiment) at Halley. Continuous VLF/ELF radio wave power, polarisation, arrival bearing, maximum/ minimum, and impulse counts, in 10 frequency bands from 300 Hz to 10 kHz with a 1 s time resolution. For a complete description of the data, please see the Chapter 9 of the BAS VLF/ELF/ULF Data Manual, on the intranet at basweb.nerc-bas.ac.uk/local/uasd/documents/manuals/dataman.pdf
