Amplitude and phase for narrowband transmitters at
ABOVE site Lucky Lake, Saskatchewan, Lat: 51.15, Lon: -107.26. 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.
Please include the following in any publications using this data: Infrastructure funding for ABOVE is provided by the Canada Foundation for Innovation and the province of Alberta. ABOVE data used in this work was collected with the support of the Canadian Space Agency Geospace Observatory (GO Canada) contribution initiative.
