Amplitude and phase for narrowband transmitters at
ABOVE sites. The Array for
Broadband Observations of VLF/ELF Emissions (ABOVE) Level-2 CDF
files of Amplitude, Phase and Bearing at 1 minute resolution for
seven VLF transmitters as observed from each station of the ABOVE
array.
The VLF transmitters observed are:
NDK (LaMoure, North Dakota, 46.37 N, 98.33 W, 25.2 kHz)
NAA (Cutler, Maine, 44.64 N, 67.29 W, 24.0 kHz),
NLK (Seattle, Washington, 48.20 N 121.92 W, 24.8 kHz)
NWC (Exmouth, Western Australia, 21.82 S, 114.16 E, 19.8 kHz)
NPM (Lualualei, Hawaii, 21.42 N, 158.15 W, 21.4 kHz)
NRK (Keflavik, Iceland, 63.85 N, 22.45 W, 37.5 kHz)
WWVB (Fort Collins, Colorado, 40.68 N, 105.05 W, 60 kHz)
GO-ABOVE is a ground‐based array of VLF radio receivers located across Canada and run as a part of the Canadian Space Agency's Geospace Observatory (GO). The ABOVE instruments are situated in two north‐south chains in Alberta and Manitoba, through the region roughly from L = 3 through L = 8. The ABOVE instruments monitor electromagnetic waves in a frequency range from 100 Hz to 75 kHz, covering chorus and hiss emissions as well as U.S. Navy transmitters near 25 kHz. The absolute timing accuracy is 10 ns, from GPS.
