Updated Repository. Added SpectralRange, ObservedRegion, InstrumentID. LNG GO-ABOVE the Geospace Observatory - Array for Broadband Observations of VLF/ELF Emissions, 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 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 summary plots span 1 second long and are taken 5 minutes apart from multiple stations in the GO-ABOVE array. Each plot contains 4 dynamic spectrograms, two for the North-South antennas and two for the East-West antennas. For each pair one spectrogram spans a frequency range of 100 Hz to 10 kHz while the other spans from 100 Hz to 75 kHz. Following the four dynamic spectrograms are two amplitude vs. time plots for the North-South and East-West antennas. A directory tree structure allows access to these files. Each station has a separate directory below the year, month and day. Within some of the month directories is a data availability chart. ABOVE data is openly available. We request that users, at a minimum, acknowledge our funding agencies when data is used in publications and/or presentations. Below is an example acknowledgement for consideration. “ABOVE is a joint Canada Foundation for Innovation and Canadian Space Agency project developed by the University of Calgary.” spase://SMWG/Person/C.M.Cully PrincipalInvestigator spase://SMWG/Person/Leonard.N.Garcia MetadataContact spase://CSA/Repository/UCalgary UCalgary Space Remote Sensing Open Data Platform https://data.phys.ucalgary.ca/sort_by_instrument/vlf/GO-Canada_ABOVE/summary_plots/ PNG spase://SMWG/Instrument/Gillam/VLF Waves.Passive RadioFrequency Earth.NearSurface.Ionosphere Dynamic Spectrogram ACElectricField RadioFrequency .1 75 kHz
